MMAPI: Moto Q8 emulator fails [message #570651] Tue, 13 January 2009 20:46

I'm working on a program which makes use of Midi playback. Now I
encountered an odd problem. Just by random i picked up the Moto Q8
emulator. My program successfuly runs on all other emulators I've tried.
So I tracked te problem down to the simplest possible example to show
the problem. The crash happens in the constructor of the canvas class.
Since it works on all other emulators I've checked, I ask myself what's
wrong with my code or what's wrong with the Moto Q8? I'm really clueless
here.

TIA,
Hans
