--- Comment #1 from cnbiz850@sohu.com 2009-10-01 11:03:51 --- Some update.
Actually, when it happens, as I press "normalize/maximize", it doesn't really shrink and enlarge by a few pixels as I mentioned last time (I had a wrong impression last time). There is some flicker when I press "normalize/maximize", but the size stays unchanged. Now I also mentioned last time that some winecfg operations can bring it back to normal. This is only true on my old computer. On my new computer, it no longer works (it worked once before I last reported). Also, if I press "minimize", it then shrinks to the panel, but it won't get normalized when the icon on the panel is pressed. So in summary, it can not be controlled by Linux window manager, except that "close" still works and also it can be dragged with a mouse. This behavior seems only relating to this one particular program. Don't know why.
I am running Ubuntu 9.04 (with Gnome of course) fully updated on both my computers.
