well your talking about the vbulletin editor right which is there code. Thus there is not much for me to be able to fix.
I would actually need to duplicate the actual issue to respond yet have showed 2 examples that dont have any issues probally an issue resolved in vb4 who knows.
I can take a guess at the
vb bug you have and probally say it comes down to there use of relative links everywhere. You could probally resolve it by copying the
vb clientscript directory beneath the reviews directory unless you go code diving into
vb files and correct the relative link to the clientscript ieprompt.html file where ever that might be.
