--- Comment #50 from Andrew Gaydenko a@gaydenko.com 2010-05-10 02:21:45 --- I have not tested as far as I'm not aware about (and have not) Windows apps at all, except for LTspice and another free app (last one has not MDI).
BTW, current bug description is misleading, as far as initially the bug included two parts in accordance with first message. Currently the second one is remaining. Is it possible to rename the bug with more corresponding and speaking to wine team manner?
