------- Additional Comments From nshmyrev@yandex.ru 2006-13-10 11:49 ------- I've investigated MWM case. The problem here is that MWM doesn't add functions to default transient functions with functions hints. The only way to enlarge set of transient functions is to set default resource. In that case you'll get minimize/maximize even on transient windows.
Heh, I really wonder if MWM need some fix.
