--- Comment #25 from DonJaime@freenet.de --- Test results submitted, volunteered to be maintainer. Not sure what a 'Super Maintainer' is; you're unlikely to find someone with access to and interest in all FMPro versions.
I see there are quite a lot of bugs involving keyboard input with various applications. Fixing this one might help them as well.
I would be willing to compile wine with debug symbols enabled and do a debug trace if someone can tell me which channels to specify.
