Corrupted Preferences?
in user/Library/Preferences all of the com.apple. .plist files have a strange additional 7 digit ending (e.g. com.apple.iApps.plist.1aEuAYE)
Also, when I try to scroll down within the Preferences window, the window will disappear and reload, always back to the top listings.
Even stranger: this happens only in column view, the strange file name extensions and scroll problem disappear when I switch to icon or list view.
