FWIW, you can find the version number in the log file. I've noticed a slow down as well, but wasn't sure if I changed my config somehow to cause this to happen so I didn't report it. I've also noticed that I'm seeing more windows popping up than I used to. For example, I've started seeing Project64 open prior to maximizing. In the past, I would just see a black screen until the game loaded. I've seen some similar things with MAME as well, so perhaps the hide desktop functionality has changed somewhat. Anyway, I haven't done any legwork to help, this is just a heads up to see if Tom or anyone else has noticed this.
