Gmail problems

[Peter Semple]

I am having two problems with gmail (version 0.7.0) Webmail version1.4.1  
One problem is that I have to reinstall the Gmail add in every 2nd or so 
time that Thunderbird starts.  It starts up with no mention of the gmail 
add in in the add in manager and I have to reinstall.  
Second problem is that I can't send any emails through the Gmail 
system.  I receive them fine, but get error messages every time I try to 
send.
