open new sub-stack with different record from database

[mfstuart]

Hi Jan,
Thanx Jan. I'll play around with that this weekend.

BTW:
1) I guess RunRev doesn't "natively" support MDI?
2) And in YOUR script after the 'set the name of it...', I should insert: go
to stack "EditAccount"?

Thanx,
Mark Stuart
