thunderbird 0.9 problems

	The behaviors seem to have changed again. The most noticeable is that when I 
click on a URL in a message in thunderbird, if the default browser is already 
open, it is not given focus on the desktop. It will either stay in the 
background, or if minimised, stay minimised. My default browser is Firefox 1.0. 
This could be a firefox issue though.
	Second, I have had several hangs requiring forced quits. It appears to be a 
deadlock situation where I have just clicked on a menu command and the browser 
has something else happening, possibly incoming mail. I do have several mail 
filters defined and the processing they instigate may be related.
	I did not havr these issues with version .8 and may go back as the deadlock is 
happening frequently.
