Oh I forgot all about this post. And I started it! Lol. Anyway - I have since just stuck to the olde Windows... for better or for (mostly) worse, because it's just what almost everything is for. When I had a mac, it would have been super useful for testing more quickly. Unfortunately WINE is hit or miss. It's likely not an easy fix for Gernot because WINE is very complex, and finding out what the issue is can be more trouble than it's worth. Use a VM if you must.
