I am showing a Progress Dialog during a long interaction with another
device.   In the middle of this, I need to ask the user a Yes/No
question.  I am currently doing this with a FrmDoDialog launched modal
dialog.   When I return from that dialog, I get a nasty "bus error".  
IF I do a PrgStopDialog before calling my modal dialog, then I get a
"Null progress ptr" from Progress.c(161).

Now, if instead of using my own form & FrmDoDialog, I put up an alert
using FrmCustomAlert - it shows up and doesnt crash.  BUT it doesnt
return to my progress dialog either...

So,
1. What is different between FrmCustomAlert and what I do with
FrmDoDialog?
2. Why does the ProgressDialog go away when I use the
FrmCustomAlert...

Much thanx in advance - I'm sure that I just dont understand yet
exactly what happens with forms and redrawing in this situation with
modal dialogs..

Gary,

Some excellent development resources can be found at www.falch.net,
particularly, IMO, the news groups at news.falch.net (lot's of answers
to lots of development questions.) :-)

This specific group tends to be discussions above the code level --
though there is a good chance someone here will know the answer to
your alert / dodialog question. 

Good luck with it,
Frank
