Slow CGI

Hi,
I have recently made a CGI script that have a very slow answer time (it executes a lot of queries on a remote mainframe) and the Microsoft IE3 have a strange behavior with this CGI (and possible others). When I click the
Submit button I don't get the Hourglass cursor  nor the message "Web site found. Waiting for reply" at the status bar. I know that it works because in few minutes I have the answer but I'm afraid that my users could click the
submit button twice or more expecting  some kind of message or cursor changing. What can be
done to solve this problem?  
In this case, how do I send an intemediate page with some message like "Please wait... Processing" ?

I'm using VB5 with the MS IIS3.0 web server (NT4 SP3).

Thanks.

By all means reject my answer, the one by Philippe sounds much better.

Philippe. Is it possible to disable cgi output buffering on a per-script basis or is it a supervisor type operation?

Phjlippe answer is good but I think there is another way. I recently bought some CD's on the Internet and when I pressed the Submit button (for processing my invoice and the Credit Card), a page containing "Wait, processing your credit card" came on the screen and after a while that page was SUBSTITUTED (not appended) with the answer of my Invoice. I’m sure that there was no <META HTTP-EQUIV="Refresh"> because the data was posted and there was no Javascript. That CGI technic is what I’m looking for.
