Well, in any case, thank you for the fix.
I know this is a bit offtopic but while we're talking about mIRC in Wine, there's one other issue that's been there since I started using this setup and that I've never been able to solve.
It's a minor annoyance, since everything else works perfectly fine. But emojis simply won't show right, they usually appear as empty boxes or something. I tried installing custom Wine fonts and everything but nothing I tried seems to fix it.
Do you maybe happen to have any idea why this is happening and if there's something I can do about it?
