pixmap problems with gtk+ for win32

[Randy Rueckner <unicorn minet uni-jena de>]

hello there!

i wrote a little application, that used pixmaps to display mrt pictures.
this application runs fine under freebsd, linux, solaris and cygwin. now i
want it native under win32. i build it via mingw-1.1, glib-2.0.3 and
gtk+-1.3.0. it compiles fine and starts, but there are no pictures shown.
the field, where the pixmap should be is black or sometimes gray.
it would be really nice, if someone can help me.

thanks in advance
randy
