Forum Unable to view any replies using threaded mode after upgrade to 4.0.1
 

If display = threaded, clicking on ANY reply results in a very brief display of the selected reply followed by an immediate return to the first post in the thread. Post replies are only viewable if opened in a new window.

If display=linear, replies display as expected.

If display=hybrid, the links to replies don't seem to do anything

This happens using the latest versions of both Firefox and Safari on Mac OS 10.5.8

This happens on my forum AND on the vbulletin.com forum

Any suggestions?
