Using beta 5 (553). When I hibernate my system at the end of the day, I don't remove the USB. When I fire it back up in the morning, I am getting a exception error dialog box on program svchost.exe. Many times, my wireless network won't work after that without a restart. Have note tried shutting down without USB/cache running. No other changes made to system, so thought it might be related to eBoostr. Did not have this with previous beta (551 I think?)
