Hi all,
A short while back there was a lot of commentary on the net about
1.2 bugs.

This may be related to the following:

Also interesting is the way the system keeps track of key-downs.  I was
playing with Disable()s and came across an interesting effect -> If I
pressed down a key before a Disable(), and then released it before the
corresponding Enable() [yes, I did expect to lose KB data], the system
held own that key FOREVER, yes, even though it was receiving key-up's
(by pressing the key again), it left the key ON.  My best guess is that
someone is counting the number of keyups vs keydowns (note that I could
clear the condition by running the experiment in reverse -> run, press
key, after Enable(), release).  Since there is no need to count
keyups/downs, I figure that something else in the chain is keeping
track.  Perhaps the WindowToFront() code locks out ints for a bit?
