Window "Set the email options" /"send the report per email" is running very slow

[Sunchaser]

Hi all,

I hope I put this message at the correct place.
Description of the report:
. Once I have ran a report, I get the option "Keep this report" and then "Email Report".
. I click on "Email Report", then the frame "Set the email options" is appearing.
Problem => it can take more than 1 minute to get this frame completely displayed. Before that all fields are not completely displayed and available, when I try to click anywhere I see in the status bar of the browser the message "a script is running slow, etc ...".
This is the only place where it is slow, the rest is working fine. The problem is that I have some users that can't wait 1 minute ... they consider it is failing, close the window and cancel the action.

Is somebody aware of anything around this behavior?
What could I do? I'm not even sure I get any warning or error message related to this in the cognos log.

Any help welcome.

Thanks!
V.
