Thanks for taking the time to answer my questions.

OK

Could you explain this of the modal dialogs. Did you have to change the
application programs to do this?

But I think it can work that way now in the code base that is in CVS. Maybe I
am misunderstanding this because the Web5250 works mostly this way in headless.

No problems. Am sure we will get around to it sometime. We all work within
time constraints.
