Bug ID: 40416
           Summary: Attempts to open some dialogs causing programs to
                    softlock
           Product: Wine
           Version: 1.9.7
          Hardware: x86-64
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]

In some programs, attempting to open certain dialogs causes the program to
freeze without responding. This behavior can be observed in the most recent
version of 0CC-Famitracker, found here: http://hertzdevil.info/programs/

Attempting to open the configuration dialog (marked by a hammer in the top bar)
will cause the program to hang. The program will also hang when attempting to
modify any new instrument.

Is there some bug with Wine dispatching Windows dialogs? This program is
developed in Visual Studio 2015.

This screenshot depicts the button which will cause the hang. The program will
continue to produce sound and the oscilloscope will continue to move as well,
but the rest of the program will freeze.
