I noticed that, when composing a new mail, saving it as draft hides the caret.
It is still there in the same place, I can type text, move it with arrows... but
it is not displayed. I have to click in the message window to make it visible
again. 
This happens only with my IMAP account, I tried with a POP3 account and this bug
does not occur.

Reproducible: Always
Steps to Reproduce:
1. Select an IMAP account
2. CTRL-M to compose a new mail
3. Type something to see the caret
4. CTRL-S to save as draft

Actual Results:  
The caret is hidden. The window still has the focus, you can continue typing,
moving the caret... but it is invible

Expected Results:  
The caret should stay visible

This happens whether you're typing in the message body (HTML or plain) or in the 
Subject field.

Confirmed, at least when I save with the caret in the body. Clicking in the body
makes it visible again.

I only use the plain text editor.

Not happening anymore. I will close, but if someone still reproduces, they can set back to NEW (or comment and I will do it).
