Just an idea...I don't have the issue Dave is experiencing but I have a similar issue at work. Whenever I try to use one of the webpages on the company intranet, it won't display properly. Yet, if I change the zoom setting within the browser by zooming in or out a few times, I can see it. Like magic, it just shows up. I always attributed it to my video driver but they won't let us update our drivers without them doing it for us. But maybe try that...it could be rendering but just not being placed properly on the screen. It's and if I remember correctly. Worth a shot. I'd laugh if that was the fix. And the real treat is that it only does that within Firefox...works perfectly in Chrome and IE. I have all 3 installed because we do have some pages that only work with certain browsers...yeah...that's fun.
