This maybe the browser your using, If i was you i would try another browser and if thats no good then ask over at vbulletin.com as this sounds like an issue for them..
Unless its a hack that you have installed that could be conflicting....
You could also try turning off recently installed hacks to se if that works!
Best not to take over derekivey's thread anymore with other issues though
Sorry derekivey for taking over your hack thread
