When I am at my inbox, click on new message, add the TO: address, then add the Subject... and then, if I click in the body of the message area, there is no cursor showing. Nor is there any letters showing up if I type on the keyboard. No respone at all to keyboard presses.

If I click on any of the HTML buttons (font size, Bold, Italic,etc), and then click in the body area, the cursor shows and and all typed letters appear.
