Safari 5: Control-click doesn't work in content area

Control-click has stopped working for me in Safari 5's content area. It works fine when clicking on Safari's toolbars and it also works fine in every other app including Finder. A complete reinstall of Safari 5 didn't solve the problem. I tried deleting every preference file and cache file I could find but that didn't help. And fixing various permissions and other things in Onyx had no effect.

Has anyone else experienced this bug? Any suggestions?

 

I'm not certain, but I suspect a beta version of the SIMBL plugin Keywurl may have caused this problem. It's the only plugin I run, and after a complete system reinstall when I upgraded to the new official 64-bit version the problem went away. For now.
