--- Comment #5 from Werner Lemberg wl@gnu.org --- Thanks for testing, this helped a lot. I know now that it is a code issue specific to Qt on Windows, and I have to patch the sources accordingly (mxe got already some reports regarding this issue, so it shouldn't be too hard to find a template that suits my needs).
Would it be possible to make Wine emit a message similar to the Windows one?
