[Bug 23180] New: TREPCAD St3: no 'close' window control (regression)

Summary: TREPCAD St3: no 'close' window control (regression)
           Product: Wine
           Version: 1.2-rc3
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: winex11.drv
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

TREPCAD3 St3 doesn't have a 'close' window control (the small x) any more.
Alt-F4 works. The control used to be there until recently.

The app can be used in two ways: as a plugin to MegaCAD and as a standalone
app. When used standalone, it doesn't have a menu bar (so, no 'File->Quit').
But it always has the 'x' to close (on real Windows and on Wine before the
regression).

I ran a regression test and the bad commit is:

commit e35e75b4bf5db54cd6cda0c95dc8c9e14c1fccfb
(winex11.drv: Do not allow WM actions for windows with WS_DISABLED style set)

Ping me which logs you need to investigate. Plain console log isn't that
useful, I suppose.
