Message editor freezes upon switching tabs

[Zyrxae]

When editing a message or a personal paper, often when I switch to another tab and back again, the message or document I've been working on seizes up such that I can't continue to add or delete anything in the message; trying to type there gives the standard system alert noise. (The insertion point blinks like normal.) Clicking on the border area in the same frame as the message sometimes is enough to make it editable again, sometimes not.

 

The more time I spend in another tab/program, the more likely the freezing, although it still seems fairly random. It happens most often while editing clickables and never when I'm editing the message/paper in a separate tab, and it occurs in Firefox but not Chrome.
