did not close properly last time it was run and will now clean up. Please then start xxx manually
Yes, I found the now-closed and long-running thread about this error message. My issue is slightly different, or perhaps here is new information.
My ongoing problem is with System Explorer. I completely deleted the entire System Explorer folder and replaced it with a fresh install. I'm still getting the error!
I had thought the program startup status would have been set or flagged somewhere in the app data or ini... BUT this seems to suggest that the error is held in the registry instead (which makes me wonder about portability, but that's not at issue here).
