Open Mycomputer from the desk top choose properties tell me how much ram is installed? Then open in Mycomputer again put your mouse over Local Disk, a small window will pop up, what does it say about Disc space it should list the total hard drive size, and amount of free space left on Disc. ******You might consider getting rid of Norton it does not get along with some PCs and there a very good free Anti Virus Programs available. Just so you know removing Norton usually requires a special removal tool to get rid of it all, if this is not done left over files will be left, it's a simple process but needs to be done correctly.

thank you for the feedback it is always good to know this kind of info in case someone searching for a clue to a similar problem may find their answer here. As to the firefox question, I had missed where you asked how to use it in your other thread, it did kinda get lost. To use firefox which you have on your pc you just go to the firefox icon on your desktop or find it in your start> all programs list and open it, double click the icon, it will open up the web browser and you use it just like you would IE, just type in where you want to go and it will take you there. Now I would guess if someone installed firefox some time ago and you never used it that it will be an old and out of date version so you probably would need to update it, you can do that by clicking on Tools> Options> then go to the update area and you have the option to choose to update firefox, your add-ons etc. I would say go to Help > about firefox and let us know which version it says you currently have and we can help you more once we know that. The link below is a good guide. Here is a link that might be useful: firefox guide

Quite a read, but the only thing I see that might apply to my situation is that I have free Zone Alarm as my firewall. It never caused a problem in the past, but I'm wondering if the latest update has something to do with this. By the way, another recent thread referring to firewalls had some interesting information indicating that ZA might not be such a good choice any more. I tried Comodo and found it nagged too much, but I'm thinking of trying the one a poster on that thread recommended. Since I have a firewall via a router, maybe I'll shut down ZA and try the System Restore. I still like having a software firewall on each computer, however.

Shayle 40 glass break sensors? Wow - that is a lot. Are they planning to mount the senors directly to the glass - or are they using a ceiling/wall mount sensor that can cover several windows in one area? I have about 12 glass break sensors in my home - and it's a good size house (5000+ sq ft). For example - one glass break sensor in the dining room ceiling covers 3 large windows. If you use the Honeywell 1625 Glass break sensor - which comes in several different styles - you can reduce the number of glass break sensors. The 1625 has a range of 25 feet. You might check out this site: http://www.aesecurity.com which is where I purchased all of my alarm parts. The site is useful since they provide data sheets on all of the sensors and you can read about their capabilities (and see what they cost). Be very very careful when dealing with alarm companies - they make their money by charging you per sensor or per zone - so the more sensors or zones they can cram in - the more they make. As far as zones - you can have multiple sensors tied to a single zone. For example - I have 3 doors on the front of the house where one can enter - the front door, the door through the garage, and then a side patio door. All 3 of these doors have a magnetic sensor - but they are tied to 1 zone. This is commonly called "sensors in series" or "in-series" connections. Obviously- the more sensors you can group in series, the fewer zones you need on the controller and that can allow a smaller alarm panel or fewer zone expander modules. Another thing to watch out for is the fire monitoring. In my first house, the alarm company refused to tie the alarm system into the house smoke detectors. Instead, they charged me a few hundred dollars for an additional smoke detector that was only tied into the alarm system - and not connected to the house smoke detectors. It was a bunch of bull. A good alarm company can make a tiny little device that allows the 9 volt traveler wire in your house smoke detectors to be monitored (it's the red or yellow wire on the smoke detector). This little traveler wire is what is used to set off all house smoke detectors when only one detects smoke. The alarm company can monitor this signal. If they tell you they can't do it due to code - have them install it after the final inspection. It is a lot cleaner to use your existing home smoke detectors then to have 2 sets of detectors. The Vista 20P panel might be too small for your system if each of the sensors has a dedicated zone. However, if some of these sensors are grouped in series, then it might be fine. In my house, I have 12 glass break sensors (each one on a seperate zone), 10 magnetic sensors on doors (3 zones), 3 CO sensor each on a seperate zone, 7 motion sensors each on a seperate zone, and 1 fire zone. A grand total of 25 zones and 32 sensors. I also have 3 keypads. I used the Vista 20P and 3 zone expander modules. In the future I paln to add a few more glass break sensors in the basement as well as some exterior IR sensors.
