Hiding Parameters in Report

I'm using a URL to execute reports and I wish to have the parameters not displayed to the user. However, when I either uncheck the Promt User box or delete the prompt string, I get an error stating read only parameters can not be changed.
We have installed SP1 on the server so I thought this issue had been fixed.
TIA for any help.

rc:Parameters=false to the URL.
If you want only some of the parameters displayed, then for those that
should be hidden, make sure "Prompt User" is checked and the prompt string
is empty.
