>Basically you copied code from you don't know where,
True, why reinvent the wheel (copied code from winecfg)

>minimizing doesn't work but that's not a bug, 
as far as i can see it looks like regression

>and I shouldn't be picky and accept a big crappy patch anyway. 
I admit i'm just a hobbiest, but somehow i was hoping you could point me to what
the "crappy" parts in the patch are, so that i could improve it, but i already
gave up that hope.

>Do you really wonder why you have trouble getting it committed?
Maybe i was just hoping for some positive feedback, but i'll stop wasting yours
and my time
