In this case it has occurrs when I'm running IE in the Win7
console. This morning I was able to enter a few characters of a
URL when it locked.
At that point, I can generally move the cursor out of the
virt-manager console to other, unrelated, xterms, usually, but
not always, being able to enter from the keyboard. Several times
this morning while working in other xterms, the virt-manager
console has grabbed focus from that window.

I *THINK* it's normal X11, but I don't know. Jeremy or somebody
on the XQuartz group can better answer that question.

which they use or do not use.
