[MinimizeToTray] minimize options

[Bart VdB]

Hi,

Everytime I have to startup Thunderbird, the MTT options I've set before 
are gone.
This means each time I want to minimize I first have to go to the 
options to activate: always minimize and minimize on close.
I suppose this shouldn't be the case.  What went wrong?
I've got the latest Thunderbird (1.5) and the latest MTT.
Thanks for your help.

Best regards
