When using the file structure windows (new in Resharper 2.0), it will eventually stop drawing its contents...the entire window will go gray. Closing and opening the windows does not fix this. Closing Visual Studio and opening it again (making sure all instances are closed), will allow it to work again. This problem is easily reproducible, and happens every time I use this window, after enough time. The easiest way to reproduce it is to open a large solution (Many projects), open the file structure window (doesn't matter if it is docked or not), do a rebuild, and the start a debug session. Some times it takes a bit of time before the corruption occurrs.
