It's not clear that an alpha channel is even meaningful with a DDB, did you test that case?
The app loads the bitmap using LoadBitmap(), i.e. it gets loaded without creating a DIB section, then the app assigns it to "Static" control. Calling BitBlt() with that bitmap as a source and a 32-bpp DIB section as a destination works just fine under Windows and Wine, and the result preserves alpha. Is that what you mean with testing a DDB?
