[Bug 27165] New: ffdshow A/V config tool: drop-down list doesn't appear

http://bugs.winehq.org/show_bug.cgi?id=27165

Summary: ffdshow A/V config tool: drop-down list doesn't appear
           Product: Wine
           Version: 1.3.20
          Platform: x86
               URL: http://sourceforge.net/projects/ffdshow-tryout/
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: comctl32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

In ffdshow's audio/video configuration window you can choose which decoder you
want to use for different A/V formats.
A drop-down menu should appear automatically when you select a decoder for the
desired format.
The menu doesn't appear in current Wine.

Actually, there is a way to make the menu appear: press and hold left mouse
button on the selected field (under Decoder tab). While LMB is still pressed,
move the mouse up or down by a couple of pixels.

Workaround: native comctl32.

This 'feature' worked correctly in Wine-1.1.2:

comctl32: Set listview focus on WM_LBUTTONUP instead of WM_LBUTTONDOWN.

To reproduce the issue in the application:
1) Install the app as usual: at the end of installation choose the option to
run the config tool automatically.
2) Under the Decoder tab select a field (containing either disabled or
libavcodec) >> the drop-down list doesn't appear.

The config tool can also be launched by:
wine rundll32.exe ffdshow.ax configure
