Similar to "psr", I experienced some problems after installing 2.3b7. Although the program didn't crash, by default, it was set to "manual", and all of the settings on the various tabs were set to the far left without exception. In other words, all of the presets in the pull-down menu were useless, because their settings on the tabs were set to the far left...every single one of them. I am likewise going back to 2.3b6 until this issue is fixed.
