While typing an email the entire message disappears from the screen with the blank email message remaining on the screen. The email has not been sent, it simply vanishes. Usually I am able to retrieve the message using the "back" symbol. However, the continuous [also] problem with menus popping up sometimes prevents my recovering the message due to the pop-up menu blocking access to the back icon.

Any suggestions?  This is very frustrating, both problems.
