I took my 09HR to work today and repeatedly cycled the power; I was getting about 70% freezes with 1.05 - the highest incidence rate ever. Tried some setting changes that I might possibly have tweaked, just to be sure it wasn't an odd combo of internal configuration.
Just got home, restored 1.04, and have cycled the unit half a dozen times with no problems. I'll keep doing this with different settings until I'm convinced, but it looks very positive at the moment.
