I tried to edit the title of another thread to avoid some confusion, but I think I just made things more confusing:
The problem is the application launcher from mouse actions on the desktop launches apps twice.
Found the bug report relating to this issue. See the following, starting down at comment #8:
So, there's a patch, "get rid of duplicate connect." Is this something that will get fixed soon in Fedora, via updates?
Sorry for the confusion with the other thread; can it be deleted?
