Fonts Change When Composing Emails In Thunderbird 3.0b2

[Robert L Cochran]

When you compose an email in thunderbird-3.0-2.1.beta2.fc11.x86_64 and 
the default font is an HTML font, for example "Nimbus Roman No9 L", 
there are times when you can be typing away happily and when the first 
line of text is almost completed, the font suddenly changes to "variable 
width". To fix it I have to select the "variable width" text and change 
it back to the desired font. Maybe it's my clumsy fingers executing a 
keyboard shortcut without me realizing it?
