I recommend to switch to the development version of Wine if you're
doing debugging like this.

I can't answer the core part of your question I'm afraid. I'm curious
though why this would make a difference. Does the VM place something
on the stack that the message handler expects to find? If so, how does
it find it? Does it expect a certain stack depth as well?
