[Bug 23500] New: Steam windows won't close sometimes

http://bugs.winehq.org/show_bug.cgi?id=23500

Summary: Steam windows won't close sometimes
           Product: Wine
           Version: 1.2-rc6
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Windows in the current ("new ui") Steam sometimes refuse to close. They start
to fade out as if they're going to, but then pop back up.

I can consistently reproduce this via..

1) Right click the system tray icon for steam, and click "Library".
2) Right click the system tray icon for steam again, and click "Friends".
3) Try to click the close button on the steam Friends window. It will not work.

Note #1: The order seems semi-important. I don't know why, but it apparently
doesn't work AS consistently switching 1 & 2.

Note #2: http://bugs.winehq.org/show_bug.cgi?id=23353 this same bug marked as
solved is not solved. I replied, but it was not re-opened and I see nowhere
else to request it to be re-opened manually, so I'm assuming I needed to post a
new report. Many apologies if this was not the case.
