IDE bug

[Jon]

I had placed a Player off the visible portion of a Stack.  I wanted to 
get it back to being visible, so I looked at its properties in the 
Inspector and clicked one of the arrows (I think up arrow) to the right 
of the negative number that represented the Top.  That number became 
reasonable automatically, and the Player became visible.

A second later, the Player jumped down a pixel.  A second later, 
another.  The IDE locked up, with none of the buttons responding.  I had 
to kill the IDE from the Task Manager.

I suppose this could be another repeated/recursive call, where the IDE 
tries to adjust something and a competing Handler tries to do something 
else, but if this is the case, I am not aware of which handler it might be.
