Seabass, pretty much any program or window will do this to the dock. But I did find out a strange thing that makes it work: winamp. It seems that whenever winamp is open, unminimized, and set to not display always on top then the object dock thumbnails will work properly. FYI, I'm using the latest winamp with big bento skin on xp sp2.
Hello! I've just started using the objectdock a week ago and I've set the bar up just for showing open windows/apps. When using minimized thumbnails the bar will lose the last thumbnail image (and replace it with its icon) of a window/app whenever another window/app on the bar is closed. Can anybody else confirm this behavior, or is there some setting or tweak for fixing this? Right now I'm using objectdock ver 1.90 build 536 on windows XP (32-bit) with latest video drivers for 8600 gts.
