Extra info regarding previous post-- I can't go back and edit that one for some reason...
I've never used any version on this system prior to version 3.2. But the 3.3 version is a Beta, if that matters, but it was installed after I had the problems with the 3.2 version. So presumably it has nothing to do with those 3.2 issues.
Also-- a previous poster mentioned a windows update having to do with graphics-- I don't know about updates. My system has been up and running for a week(-ish) since the last reboot and before the problems began. However, I do note that the last entries in the logs seem to have something to do with setting up for graphics of some kind. Perhaps there is a connection here?
