Today I discovered what seem to be two bugs in 2.0v2.  Apologies if this
topic has been discussed before.

Here's two quick ways to crash the system with error #04 (whatever that is).
In the message box, type:

   1)  3 div 0
   2)  the number of lines of cd fld "nonexistent" div 2

#1 crashes instantly.  #2 gives you an error message, saying there is no
such field, and then crashes when you click on "Cancel" in the error dialog
box.

Yes, this happens when I turn off all my INITs, and it happens in different
stacks, including starting up with completely empty home stack.  Haven't
tried it on any other copies of HC besides my own, so maybe I just have a bad
copy (although I got it straight off the Developer's CD!).  But before I
researched more extensively I thought I should find out if this happens to
other people.
