Comment 7 for bug 348028

I have the same problem on a fully updated Jaunty (amd64). After compiling a document a couple of times and editing in between, the editor does not accept keyboard input any more. Mouse still works.
Interesting: The keyboard shortcuts to access the menu Alt + something also work. And if I click in "structure" on "LABELS", the editor suddenly accepts input again. If I click on the editor window, then, the problem is there again. So this might have to do something with the focus?
The problem with headers not appearing, TerpInHotLanta mentioned, does not apply for me.
