Maximum PC

Ebays country choice pop up keeps popping up.
I've checked the appropriate block on multiple occasions. Yet it keeps coming back time and time again. It doesn't seem to matter if I'm using Vista or Win 7, it will go away for a while. But some random time later, it's back.
I've sent an email to them about this in the past. Three times so far.
So today I've sent another (number 4), this time with stronger language and several words (several STRONG words) all in caps.
I am getting more than just a little miffed with that damned pop up.
