bug#25842: 25.1; Mouse stops working after using Logitech mouse's minimize button

[-- Attachment #1: Type: text/plain, Size: 3672 bytes --]


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".

Thanks, but please provide a full reproduction recipe starting from
"emacs -Q" and including the minimal customizations needed to change
the mouse click to perform the "minimize" function.  We need this to
be able to investigate the problem.

Also, are you mentioning that specific Logitech mouse because you can
only reproduce the problem with that particular type?

bug#25842: 25.1; Mouse stops working after using Logitech mouse's minimize button

[Robert Ross]

Eli,

This fails the same way when running "runemacs.exe -Q".  No customizations
required for Emacs.

I mentioned the specific mouse I was using, but I've checked two more mice and
believe any Logitech mouse will work (I haven't tested for similar
functionality in other brands).

Older mice are supported by SetPoint, and newer mice are supported by "Logitech
Options".  Either version can be downloaded here:
http://support.logitech.com/en_us/product/wireless-mouse-m510

If using a SetPoint mouse:

Install Logitech SetPoint
Run "Mouse and Keyboard Settings" (SetPoint) to customize buttons.
   Select a button, but not Left or Right
   Select task "other" for the button, scroll down to find "minimize"
   Apply

If using a "Logitech Options" mouse:
Install "Logitech Options"
Run "Logitech Options"
   Click a button that you want to customize.
   Select "Minimize Window" as the action.
   Close the window

For either option:

Launch Emacs.  See that the mouse works normally.  Click the "minimize" mouse
  button to minimize Emacs (just click somewhere in Emacs, not on the little
  corner button)

Restore Emacs.  Note that the mouse buttons no longer work.

Click one of the menus (File, Edit, etc.).  The next click inside Emacs
  doesn't work, but subsequent clicks do.

Thanks for your help.

(I'm going through old bug reports that unfortunately got no response at
the time.)

Are you still seeing this problem in more recent versions of Emacs/Windows?

This kind of bug needs someone who can reproduce it run Emacs under
GDB and see what kind of events this mouse sends to Emacs.  Or use
some tool (not that I know of any off the top of my head) which will
show the messages Windows sends to Emacs when clicking this mouse
before and after the problem begins.  I don't see how can we make any
progress here otherwise, sorry.

I installed the mingw-w64 version of gdb (8.1). I've been poking around looking around for how to capture mouse events but I'm not seeing anything obvious. Is this an easy thing to capture, or will it take some expertise?

Look in w32term.c, where it processes these messages:

	case WM_LBUTTONDOWN:
	case WM_LBUTTONUP:
	case WM_MBUTTONDOWN:
	case WM_MBUTTONUP:
	case WM_RBUTTONDOWN:
	case WM_RBUTTONUP:
	case WM_XBUTTONDOWN:
	case WM_XBUTTONUP:
	case WM_MOUSEMOVE:
	case WM_MOUSEWHEEL:
        case WM_MOUSEHWHEEL:

That's where the processing of mouse events starts in Emacs.

Robert, have you gotten any further debugging this?
