Another problem I've got is that when I'm opening a program, it runs fine. When I switch out of it (Alt+Tab or just going to another window), my computer becomes extremely laggy. I checked my task manager (another problem explained in a dif topic), and when I looked at the priority of the process, it was set on Low. I never changed it, so I decided to.. Change it to Normal. After going back to the program, it became ok again. Until later when I switched out of the program again, the computer became laggy. I looked at the priority - Low.. How is it automatically changing? Can I change that? Can I set the program's priority to be at default Normal (I've tried the cmd.exe c/start /normal "program.exe" but it didn't work)?
