I'm using Audacious media player in Winamp 2.x skin mode. It consists of two windows: the main window with playback controls, whose title shows the current track, and the playlist editor window, whose title is constant. These windows are grouped into one Plasma Task Manager button on the panel, even when Task Manager has plenty of space. This is good. The problem is that the text displayed in Task Manager for Audacious shows the current track in Audacious when it was started. Playing a different track in Audacious doesn't change the title displayed in Task Manager. In alt-tab, the title does change. If I close the playlist editor, then the title changes in Task Manager as I change tracks in Audacious. So apparently the way Audacious windows get grouped causes the problem.
(Separate Firefox windows group differently, only grouping when Task Manager is full, and then using the name of the application, with a + icon.)
