Your code is indeed an improvement as it really works under solaris with
gtk-0.9.13 and under (SuSE) linux with gtk-0.10.1.

(It also does not end in "SystemziGlibziGObject_d1xz: interrupted".)

If it works for you with gtk-0.11.0 then surely only, because of your
patches.

For the released gtk-0.11.0 version your dialog-code also blocks like my
 code.

Are you making a new release? Or do I need to get gtk2hs from darcs?

My program will probably not run under windows since it does also does
not run under solaris at least with older gtk releases.

I wanted to know, if something is wrong in the way my program was
written. (If so, I've got to change it.)

I'm going to test this. Does my version work for your patched gtk under
linux? (If not, it will probably not work under solaris, too. If yes,
why should I change my program?)
