Recently (last week) my window manager key bindings stopped working
after I minimize XWin window and restore it or resize it. My
combination of Alt key and mouse clicks do not work anymore.
I use kind of exotic window manager (ctwm) so to make it easy to
replicate I used xev to repeat the same Alt + mouse click sequence and
captured the xev list of events before and after XWin minimize and
restore. It looks like the list of events listed changes drastically
explaining why ctwm stopped behaving properly. I see the same behavior
in Win8-64 and Win7-32. I see that Alt key stopped working as a
modifier. I tried twm instead of ctwm with the same result.
Here is the output of xev before XWin minimize/restore or resize while
pressing Alt and clicking left mouse button in xev window:
LeaveNotify event, serial 32, synthetic NO, window 0xc00001,
root 0x16d, subw 0xc00002, time 118362968, (41,42), root:(1747,393),

focus NO, state 264

0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
Here is the output of the same actions after XWin minimize/restore:
KeyPress event, serial 38, synthetic NO, window 0xc00001,
root 0x16d, subw 0xc00002, time 118672828, (49,36), root:(1755,387),
