--- Comment #6 from Jerome Leclanche adys.wh@gmail.com 2010-12-03 23:44:56 CST --- """ this is what I found so far, fuhrter investigation is pointless until this doesn't work:
1) Apparently, WM_CANCENMODE message sent to the owner of a menu does not cancel the menu. This causes serious troubles to the menu management. 2) When creating button in the toolbar, WINE ignores I_IMAGENONE in the TBUTTON::iBitmap member. The created button still looks like it has a bitmap, even tho empty.
