--- Comment #25 from Andrew Eikum aeikum@codeweavers.com --- This commit is in Wine and should fix this issue, including for your existing prefixes. You can test it if you're capable of making a 64-bit Wine build. Otherwise, wait for your package manager to release Wine 1.7.43. Please report back when you test it to confirm that it's fixed!
