The only way I'd found to make it work as it should has been to reboot. I don't like to reboot so that wasn't acceptable to me.
The other day I Googled it one more time.
I found it. A couple of screens down in the Google results was this forum post.
f0dder's answer was so simple. I should have thought of this myself.
To solve it, bring up the task manager, *exit* it instead of minimizing, and re-start... at least that works for me.
