I have started getting some crashes that are ReSharper (5.1.1708.23) related. After some time editing and debugging, normal usage, I will start to get yellow boxes in the lower right of the screen. Sometimes they show text in an odd font, something about an exception or a GDI+ error. They will appear and disappear very quickly over and over, eventually stopping. At that point, the whole VS environment loses its ability to display dialog boxes. If I try to bring one up it will close immediately. After a few more seconds of this, the entire app crashes.
Here is a screen shot of the yellow box.
This never happened with the release 5.0 version. Suspending ReSharper from Tools|Options eliminates the problem.
Note that no exception dialog comes up. I only get the standard WER dialog from Windows and VS then restarts itself.
