Same thing here.
As I have developed my site, I as most doing this stuff, use Firefox due to the add-ons strength etc.
So, faults that may pop up in Explorer, I didn't even think of.
Say what you want, but I have never had trouble with Explorer, and it doesn't suck up memory like Firefox either.
Anyway, that discussion aside, the other day someone asked me why they can't get the Connections (Friends) to work...? I thought, geez, this is an idiot...
Then checked in IE7 to see for myself.
Wow, there was no popup window with message abilities like in the Firefox!
It was a white field saying "False".
I have tried finding a solution here somewhere, but seems to be not available, or even known.
Anyone?
