Thanks, I believe I have to use ScreenSaverDefaults, then? because
the documentation for ScreenSaverDefaults says:
"Because screen savers are packaged as bundles and loaded by several different applications, it is not possible to use NSUserDefaults to store user preferences for them."
I was just a little bit hesitant to use the regular ScreenSaverDefaults for those really small pieces of data that change every time,
because I already use the ScreenSaverDefaults to store quite a bit of other data (that changes only rarely) , in total 15 MB.
That means the OS has to write all of that data back to disk just because I have changed an integer,
doesn't it?
Best regards,
Gabriel.
