--- Comment #2 from Martin Thierer thierer@web.de 2009-01-23 14:59:11 --- I tried the patch from your mail (not from the one you linked to, but from the one titled "Try 2") against wine version 1.1.13 and can confirm that your patch indeed solves this bug. (For the sake of completeness, I also verified that unpatched 1.1.13 still shows the bug).
Good job! Thank you very much!
