[AccessD] Debug Stopped

Dear List:

This is a new one on me.  I have a database that does not respond to
breakpoints.  If I put a message box in the code - MsgBox "!" - I indeed get
a message box with !.  But at the point if I hit Ctrl-Break, it should break
into the code.  But it doesn't.  It's obviously in the code of that module
but it doesn't do anything that the module is supposed to do - like add
stuff to a table.

If I Dim X as variant and put x=1/0 in the code it should generate an error.
but it doesn't.

What could be going on here? (Already tried decompile.)
