Out of memory probably means you are running short on memory as you may only have the bare minimum installed. What version of Windows and which service pack are you running? How much memory (RAM) do you have? Find both by clicking Start click Control panel click System The new window will tell you which Windows and service pack and just below will show the RAM

With your setup I've found that the very low speeds prefer a spa at pool level, when the spa is raised you experience your dilemma. My suggestion is programming the computer to run the spa for an hour at the low speed in the morning, run the pool at low speed during the day, and then having the spa run again for an hour in the early evening. With this schedule you get maximum electrical savings and maximum sanitization for the spa. I disagree with mas985 on simply running at a higher speed for a half hour once daily, this body of water (spa) is the most susceptible to UV degradation of chlorine and escalation of the water temperature. If you choose his method run at least 45 minutes at high speed twice daily. I also disagree with racket too, to many avenues of return and bypasses will always seem to outfox the second fox. In other words, only the plumber and the original owner get it, and many times it's just the plumber because it outfoxed the pool owner too. Plus it costs for the prices of actuators and relay spaces. IMO your better served running the very low speed all the time and doing the spa, pool, spa daily cycle thing. Just my .02 See ya, Kelly

There is lots of info from experts on google ... Here is a link that might be useful: here's a start..

Keyboard shortcuts for playback control are specific to the video player, not to the video/content datafile. Content viewed via Java, JavaScript and other such players embedded/programmed into web pages, I expect whether or not there keyboard shortcut controls depends on the whims of the programmer and it's all very non-standard.
