Pretty complicated stuff (like Booleans) work, which makes this even more curious. Also, earlier this also worked. Of course, the bug might be in Wine, if so, it needs to be reported; however, that needs some background, which I'm not competent to give. You, on the other hand, are more than competent... :D

But, very much thank you for your effort! There are not many devs who support Linux at all.
