I have IE 7 and OE 6.0029.

I don't remember if this started happening before or after I upgraded to
IE 7, but I cannot change the font size in OE messages I compose. It
defaults to 12 and cannot be changed. I can change the font from Arial to
any other style, but not matter what font style I use I cannot change the
size.

Does anyone know what the problem is and how I can fix it?
