--- Comment #15 from Mark K markk@clara.co.uk 2012-12-14 07:32:45 CST --- I tested PuTTY 0.60 with wine-1.5.19-74-g4bb92e1 and the problem seems to be fixed. However you need to disable the "Allow the window manager to decorate the windows" option in winecfg first.
I didn't do a regression test to see which commit fixed things, but it may well be the same one which fixed bug 32394. (Bug 32394 may effectively be a duplicate of this one.)
winex11: Send WM_EXITSIZEMOVE when the mouse has been released. http://source.winehq.org/git/wine.git/commit/ed47a507d0ec9b1d5771ea86b4b7fb2...
and/or possibly winex11: Send WM_ENTERSIZEMOVE when starting to poll for a window move/resize. http://source.winehq.org/git/wine.git/commit/91ebca2bf10e3ef5edcb65868a8f3ce...
[I noticed a problem when the "Allow the window manager to control the windows" option is disabled as well. In that case the PuTTY window cannot be activated; keyboard input goes to the console instead. I guess opening a separate bug for that would be best though.]
