VS blocking over 10 minutes during startup

Hi there

My VS sometimes blocks for ages during startup. I can't say for sure
it's RS (haven't deinstalled anything yet), but it's the only VS-related
thing I've changed recently, and after VS unfreezes, the ReSharper
status indication is the first thing that is being displayed. Here are
the first entries of the RS log that show the huge gap between
OnConnection and OnStartupComplete:

09:45:37.078: Thread:1: +OnConnection:
09:45:37.390: Thread:1: Mode: ext_cm_Startup
09:45:37.390: Thread:1: -OnConnection:
09:57:31.343: Thread:1: +OnStartupComplete:
09:57:32.187: Thread:1: ReSharperAddIn25: initialization started


btw: Sometimes VS also freezes during closing.

Cheers,
Philipp
