... this Process you are executing...
is it initiated from inside the DIV ?
I reported a month ago some behavior where in the Destination DIV, if I opened a Form, then after the SAVE (and the close of the Form) it wiped out the DIV.
Consensus was that a DIV (and the new "output to Div" option) was only going to be useful for display only purposes... like a one-way only sending of data into that DIV
I'm not sure if this is what you've discovered now... hard to tell.
I did what you're doing now... looking at the source and seeing that my named DIV was getting wiped out after the FORM was disposed.
