Found a bug in Mail 4.4
I was checking the options at the bottom right of the screen and then a prompt to enter my account password popped up. I could only select "ok" to the prompt and could not type anything into the password query. I had to select "ok" without a password and quickly select something on the menu to relieve the ability to type in a password when it popped back up. For better illustration of this issue, please see the screen shot I made of Mail.app when this problem occurred.
