Advice as to how to create a dialog

[Mark Schonewille]

Hi Mike,

You could lock messages before opening the dialog. That should keep the 
engine from firing the openField message. A better way probably is to 
not only lock messages but also select the text of the next field before 
unlocking the messages.

I thought that I would use the open field handler and I thought I would pass data to and from the dialog stack thru the dialog data.  Sounds simple enough...
