Mozilla stops accepting keyboard input

[Ben Stringer]

I often see a fault with mozilla where it stops accepting keyboard
input. The mouse can still be used to select text, but anything typed
into (for instance) the URL text field is dropped/ignored.

Iconifying and de-iconifying mozilla will restore keyboard input to
mozilla.

Can anyone confirm that they see this problem too?

There is a bug similar to this logged, but I don't think it is the same
problem.
