Running Emacs in Windows 10 with Logitech MX Anywhere 2 mouse.  I've
changed the function of a mouse button to be "minimize".  After I
minimize (then restore) Emacs, I get no response from mouse clicks: I
can't select text or reposition the cursor.

I can still move the window and access menus with the mouse.  Accessing
menus clears the problem and I can again use the mouse normally.

This doesn't seem to be Major mode specific.  I get nothing in the *Messages*
buffer, and nothing is triggered when I select "Enter Debugger on Error".
