Hi Terry,
ok, I see what you mean, you have a lookup, on a lookup.
One small bug in your example (which didn't affect what you were showing) was that the loc:MailBox field on the FormMemory_Mailbox procedure should "reset" the AliasBrowseControl field.
If that is on, and the Lookups are done in _popup_ mode then it works.
In page mode it doesn't work because the lookup settings are not re-entrant. I'll look into that, but it's quite a big change. Would your system work with the lookups in popup mode?
cheers
Bruce
