I've configured my Font to be type Calibri with a size of 11 for composing and replying to emails. However, when I click 'New E-mail' and open the compose window, the font size appears reduced by one point while I am typing. This is only a problem when the email is being composed. The email ultimately gets sent out with the correct font size. What could be going wrong here? What should I do in order to see the correct font size while composing the email?
