I do not have this problem. Maybe QT thinks you need more help than the rest of us? ;)

Did you try repairing permissions and deleting preferences? I doubt either is the problem, but it's something easy to start with.
 
Double help menus used to be linked to a divx plugin that needed to be removed or updated... or something like that... don't remember... so do a little search, and you should find more than one thread describing this problem, with solutions... ;)
