Pls help.. button causes postback instead of redirect

[labbit]

Hi,

I'm facing an issue with a vs .net 3.0 application.

There are some users who has the following problem:
when they click on a button or any controls that causes postback,
the page refreshes without running the server-side script.
For example, when the user clicks the Cancel button,
the response.redirect is supposed to run.
Instead, the page does a postback and the same page remains.

What are the possible causes of such issues?
Somehow, this only occurs to a minority of the users and i have no idea where to start troubleshooting this...

Please advise...

Looks like the EVENTARGUMENT is not getting set for those cases. Do they have javascript enabled in their browsers OR is there any javascript error that is happening.
