Yes it still malfunctioned. But...
@All
I got it! It's the Sticky Menus. The Calculator doesn't like it and gets into some sticky fingers.

I did a test. Loaded up Calculator and pressed RAmiga-1 to get into Extended mode. My CPU meter loaded up.
So went into GUI Prefs ansd disabled the Sticky that really was making Calculator get sticky.

So then I tried re-enabling the Sticky. And ran another Calculator. It too was fine.

So I wonder why a Sticky menu would put the Calculator into a sticky? Hard bug to find?
