Running solution with VB.NET & C#, ASP.NET, VS 2008 with ReSharper 5
Most of the time, ReSharper is working (redundant code grayed out, squiggles, etc.)
Sometimes, on the same code where it was working, nothing is highlighted to show ReSharper is enabled.
I haven't done anything except modify code and debug.
What is going on that turns it on/off?
