I've installed F8 from the Linux Magazine #86 cover disk and in playing around with Desktop Effects have messed up the System/Preferences/Look and Feel sub menu.
The Look and Feel menu now contains Appearance; Desktop Effects; GL Desktop; GL Desktop; Main Menu; Screen Saver and Windows choices in that sequence.
Desktop Effects has no ikon and when selected gives the following Error "Could not launch menu item. Failed to execute child process "desktop effects" (no such file or directory)"
When invoking either GL Desktop entry subsequent application windows are unframed, can't be sized and can only be closed by exiting the program or Ctrl_Alt_Backspace.
Any help in sorting this out would be much appreciated.
