Colin,
I just ran into a problem I’ve never had before the latest upgrade. While working on a model, I went to the 3D Warehouse for something, and before I could search for anything, I got this and I can’t get beyond it.
The program is still running normally, except I can’t get rid of the window. I can move it out of the way, but can’t get rid of it. I’ve tried everything, including Windows Task Manager, but no luck. While this is not a Bug Splat, it is an obvious bug.
