I want to disable the screensaver because I run ZC in windowed mode and I don't like ZC to take up half of the CPU time to run the screensaver, especially since I don't test all too frequently and like to leave ZC open.
777:Screen Saver settings reset between sessions
Make sure you are hitting OK or Preview after you make your changes.
I do. It saves for only that session. I leave the ZC window open for quite a while.
I guess it isn't a bug. It saved this time. Weird.
