I like to do this using frames in the browser.  I use javascript in the
dispatching page in one frame - or it could be in the frameset - and the
longwinded report will display in another frame.  Before submitting the
form, I use javascript to write a message (e.g., "Please Wait...") to the
display frame.  The message will stay there until the display frame reloads
with the longwinded page.

Works like a charm, although of course the client browser has to use
javascript.

Cheers,
