Gnutella Forums - I can't click in the program

I cannot use the left click in limewire for some reason...it works fine in any other application or program and I haven't had problems. With limewire when the little question thing comes up asking you to go pro, I can't get rid of the box unless I right-click and click close....that works fine. Then it goes to the limewire page or whatever and I can't click anything in there like the search, audio, video, pictures tabs and I can't click any of the alt tabs at the top like files help navigation or view. Any idea why? I can close the window only by right clicking and clicking close as well
