I got the following when submitting an exception to the tracker:
"Request #15970 has already been fixed in build 215"
Side-by-side installation of VS2K3 and VS2K5. I first installed ReSharper
build 215 for VS2K3, started VS2K3. Then installed ReSharper build 215 for
VS2K5, started VS2K5 to verify no exceptions where thrown and then reopened
VS2K3 to verify the startup.
Anyway I was unable to reproduce this problem.
