F9 & F10: Add/Remove Software program leaves behind a running process that cannot be stopped.

[Daniel B. Thurman]

Has anyone noticed that running "Add/Remove Software" program,
after you have selected items therein, completed the installation,
or if you decided cancel out the selections and terminate the A/R
Software program, there appears in the Task Notification, a package
icon, and in it, says "Waiting for other task"?  There was nothing
that I could find in `ps' (processID) nor was there any way to terminate
the package icon since no menu item is available to do so?  The only
way that I could stop this was to reboot the system.  Does anyone have
this problem or is there a way to terminate this package icon in the task
notification area without rebooting?

Thanks!
Dan
