I can reproduce this in VS2005 (and Windows XP), with only .NET 2.0, so this isn't a 3.5 bug. I suspect it's a bug in the MenuStrip, which was new to 2.0.

However, even though it appears that there is a blank item at the end, there really isn't. You can't click on it (at least in my test with .NET 2.0, I couldn't click on it). Yeah, it doesn't look really nice, but off the top of my head I can't figure out a workaround (I really haven't adopted the MenuStrip yet ... we're still using the old MainMenu from 1.1).

But at least it doesn't affect anything negatively, since you can't really click on it ... it merely looks lousy. <g> If I get a chance, I might look at it some more though. If you figure out a workaround before I do, let us know.
