A DESCRIPTION OF THE PROBLEM :
If I have a few frames showing. Then after showing and closing modal dialog on some frame, all frames will disappear from task bar except the last opened frame. And if you close this "last" frame, it will look like Java Application closed, but you still can get some frames by Alt+Tab, however they are not showed in task bar.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) show 3 frames, you can see them in task bar.
2) show modal dialog on one of them, all frames collapse in one link in task bar.
3) close modal dialog, link in task bar was expanded in only one frame. Should be 3!
4) close this frame which have link in task bar. And task bar doesn't show links to Java Frames anymore, however there are still 2 frames are running and you can get them by ALT+TAB only.


REPRODUCIBILITY :
This bug can be reproduced always.
