Filtered KEYS --- Three Ways:
tagkey= "MD"
tagkey= "TD"
tagkey= "ST"
primary tagkeyall has no filter

>I'm confused. Do you have a filter here?
Use a parameterized view?

Barbara, I originally had Views - but the RI didn't like it:
I would enter a change to Parent--Child
Go to the Next record
Attempt to edit either
1) the second Child of the same parent
or 2) the Parent
and the system would Lock up requiring a PC reboot!
I got rid of the View - no more PC Lock up !
Does that give a hint of what I am doing Wrong?
