I like the idea here, but I can't seem to get this to work. netscape
4.5 is waiting 3 secons, then it flashes the "Awaiting..." just
before the "this is the end"
IE 4.0 just waits and then prints
--boundary
Content-Type: text/html
Awaiting query results, please wait ...<br>
--boundary
Content-Type: text/html
This is the end
--boundary--
I've been using javascript for this, I have a frame with a function
that pops up a "please wait" window and when you click the button
that runs the query it runs the function, at the bottom of the
results page there is a javascript call to close the window, it works,
but I'm open to new ideas and avoiding javascript wherever possible.
what am I missing here
Thanks
Steve
