Possible Venkman Bugs: Floating and Unfloating Views, Closing Venkman

Hi,
I'm using the newest Venkman Version 0.9.87 under Firefox 1.5.0.2 and 
Windows XP Professional (Venkman has been installed as an Extension to 
Firefox) and when using Venkman two problems occur:

1) When I add a watch expression to the watch-view and then unfloat this 
view everything works fine, the watch expression is still displayed and 
evaluated. But when I float the view again the watch-expressions are all 
gone an no more watch expressions can be added

2) When I close Venkman and all other Firefox-windows the 
firefox-process is still running and Vankman can not be restarted until 
I stop the firefox process by using the Taskmanager.

Are any of these bugs already known? Because on the official Bug-List at 
https://bugzilla.mozilla.org/buglist.cgi?bug_status=UNCONFIRMED&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&component=JavaScript%2BDebugger 
(according to 
http://www.hacksrus.com/~ginda/venkman/faq/venkman-faq.html#report-bug) 
no bugs at all are mentioned so I assume that there are no known bugs.
If this bugs are unknown, should I put them on the bug-list?

Best regards & greetings from Austria
