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..
