I've been having issues with your Quick Access and Insert Special Item tools, I didn't really figure it was that big of a deal, except when I'm drunk and can't remember how to use tags, but Bull said I should come here and say something anyway, so, here I am saying something anyway...
Ok, first off, while this is occasionally annoying, I've pretty much found ways around it by using "quickreply/quickedit" and url insertion tags, so this is just an FYI.
I'm using Vista SP2 (Which I HATE, I can't wait till Win7 comes out) and Microjunk Internet Explorer (though I've had the same issues while using Firefox).
Anytime I try to use your insertion tool for links etc, I get only error codes. I have popup blocker turned off for Dumpshock and have even had the problem with internet security turned off, hell, I tried with all my security off, including my firewall, and it still happened.
I figure it's on my end, not yours and I'm just kinda curious what the hell the problem is... My old computer (may it rest in peace *Cue Taps*) running XP SP3 never had these issues.
