Pete....
Thanks for trying. Deleting interface did not work.
I see no reason to run 32bit (and hopefully never will)

So here is updated list of things tried:

Opening a "new" file does not solve this.
Resetting to factory (full) does not fix it as well.
Reinstalling latest Patch (804) does not do it either.
deleting intrface.bbw

What else is there to try?
