--- Comment #32 from David Taylor davidt-wine@yadt.co.uk 2008-09-30 17:22:28 --- Comment #10 says the exact opposite -- that wine is acting in the way it does to work around the behavior of other window managers; and that the behavior of wine is wrong but correcting it is not trivial.
My patch, which is rather trivial, is probably missing something obvious. But it works for my test case in compiz, fvwm2, metacity and kwin. I was rather hoping someone would comment on the proposed patch rather than getting in to a protracted circular argument about whether the (confirmed) bug is actually a bug.
Apologies to everyone else on the CC list for the spam.
