Not sure, but I think I might be experiencing some sort of issue caused by classic shell (most likely, hence why I chose this forum) or CSM. It happens under unknown circumstances and causes the taskbar and title bars to stop responding until I restart Windows... and thus the only way I know to get any sort of troubleshooting information about it (ideally a workaround) would be to restart various programs that might be causing the problem, one of which is this one. How can I do that? Is there a line I can run in Command Prompt/Run to force classic shell to unload/reload?
(I can get around Explorer being unresponsive as described; got AutoHotkey and a few other things that might allow me to invoke a batch so that part isn't a problem)
As an aside, I tried searching "restart" in this forum before posting this, but apparently the word is too common. If that's not intentional (and frankly, if it were me, I would consider that definition of "common" to be too liberal. More results are generally better than none), I suggest an admin take a look at
this article I found on phpBB's forums:
