Weird glitch

[wreckwriter]

Using latest Firefox, whenever I reply to a thread, clicking "post quick reply" gives a message about the page asking if I want to leave. Clicking yes results in duplicated post. Seems to be a Vbulletin glitch.

It happens sometimes. I just delete the duplicate.

It's a glitch that's been happening for years on and off.
Just use your BACK button or close the page, don't click yes.
Your message would have already been posted (just the once) when you find the thread again and have a look.
