If i'm working along and i go up to any of the items in the task/title bar - lets say file - click and nothing happens. I click on the desktop and come back to the program and it works fine.

It is a workaround but it is tiresome and there is no rhyme nor reason to it.

Yes i run a lot of 3rd party customizations but i've turned them off and on and i still see the problem.

Any ideas? or is this a problem in 10.5 and i've missed the solution.
