             Bug #: 30784
           Summary: CodeJock's XTPToolBar renders transparent areas of
                    icons black
           Product: Wine
           Version: 1.5.5
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdi32
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: dank at kegel.com
    Classification: Unclassified


This was found while testing bug 28646, which has same symptom but different
cause.

Affects commercial apps based on CodeJock's "Xtreme ToolkitPro",
e.g. apps from tannereda.com and securenetterm.com.

To reproduce:

wget http://www.codejock.com/download/win32/TabbedToolbar.zip
unzip TabbedToolbar.zip
rm -rf ~/.wine
winetricks mfc42
wine TabbedToolbar.exe
Click on 'Other' tab

The fifth icon on the toolbar (with an envelope and a clock) has a black
background in current wine, but looks good in wine-1.5.4 and earlier.
