Problems with Seamonkey 2.35a2

Hi All

I have been using this build for a couple of weeks and have noticed 
several problems:

1] Sometimes Seamonkey does not close/exit properly - Seamonkey is not 
onscreen, not on the Windows list but when trying to start it a message 
appears onscreen that Seamonkey is already running but not responding. 
Sure enough, there it is in the Process list. Checking the Process list 
shortly after closing/exiting Seamonkey does sometimes show Seamonkey 
still running. I have tried to spot a possible reason and suspect Flash 
as every time Seamonkey does not close/exit properly Flash has been in use.

I gather that Flash is not recommended as a plugin with this build of 
Seamonkey but have no idea what to use to play Flash video when the 
libav support files cannot handle Flash playback.


2] Seamonkey sometimes fails to start "cleanly": Seamonkey appears 
onscreen, the Sidebar bookmarks get populated the cursor stops flashing 
on the url entry line and Seamonkey has crashed. Killing that instance 
of Seamonkey and restarting usually works OK. No idea on possible causes 
as this happens even if Seamonkey is the 1st app run after system 
startup as well as when the system has been up and running for a while.


Any thoughts on possible resolutions to the above?


Regards

Pete
