Yes I see that also. It's very odd - it appears the events passed from
the backend to the frontend get out of sync - as if the runloop doesn't
process them fast enough (coupled with the fact that WindowMaker insists
on sending a "Take Focus" message to a window that already has focus.)

I'll have to track down exactly what's going on.

Perhaps you can try with --GNU-Debug=NSKeyEvent and we could try to
interpret what is going on with the keysyms.

I can't replicate this, but perhaps I don't understand exactly what you
are doing.

When the window initially gets the click, it calls
-activateIgnoringOtherApps:, which orders all the windows front and
makes the key window key again (i.e. the previous key window). Then the
window that got the click makes itself key.  I'm not sure how to solve
that one.
