I've seen this intermittently, and it's mildly annoying, but now it's more so. I'm trying to open project properties. What I get is a blank page. I just discovered that the controls ARE there, they just aren't visible. If I click in just the right place, I can get the drop down to select the target framework. The controls simply aren't rendering. This happens across systems, and is kind of random and unpredictable. Normally, this happens for a form or code page, in which case closing the page and reopening will correct it, but not with project properties, or at least it hasn't fixed it so far.

Is there a means to force VS to redraw one of its tabs?
