well, there's nothing critically important on this mac i'm working at. but it's pretty annoying if files such as apps preferences or finder and system preferences are disappearing! i have to create whole new setup and workspace every time. thou, i've stored most of apps prefs on stick but can't store the whole system! for instance, last time it happened my e-mail accounts were deleted, safari history and bookmarks also, finder prefs...
just can't figure out why would one do something like that??? ok, mp3, avi, divx... but system files???
now i have created password and turned off all of file sharing options and lat's see what happens next...
thank you guys for helping me solve this and have a nice weekend!
