The way I typically would do something like this is to create a special
window for the progress bar, which could contain a label with something like
"Now Loading.  Hold your horses ..."  You could open this window in your
main window's onOpen routine; however, *do not make it a child of the main
window!*  It will need to be a parent window (aka the child is 0).  AFAIK,
child windows can only be seen when the parent is visible.

Since it's a one time window, you could declare object variables in the
onOpen routine to declare the controls, then destroy them at the end of the
procedure, before the variables go out of scope.

Hope I haven't confused you.

Happy Hunting,
