I was excited to see that build 804 was a beta candidate and recently marked Stable. However, it's not all that stable. I can crash it within a few seconds of editing an MSBuild file simply by typing in the file. This has been happening throughout the pre-EAP of R# 4.0 and I'm curious if it is on the radar to fix. Basically, I just want it to stop crashing and allow me to edit the file. I'm not expecting intellisense in MSBuild files yet.
