I'm writing a stack which does keytrapping in one of its three editable fields.
I'm using the XFCN called controlLock to turn the keytrapping on and off 
when the user goes from field to field by either tabbing or mousing. A
problem arises when the user opens the message box and keytrapping is still on.
I don't know how to detect this and turn the keytrapping off automatically.
My only solution so far is to include a button when can be used to toggle
the keytrapping manually.  I'd like a more elegant solution.  Does anyone
know how to detect opening of the message box?   Thanks.

I posted this message previously and screwed up subject name.  I don't know
how to delete messages or change the subject name.  Sorry for the 
inconvenience.      Keith
