>When I ran it on Netscape 6.2 it looked hosed (positioning was off and style attributes ignored) and the validation controls worked, but did not stop the browser from submitting the form if a rule was violated. Many other people in other NG's agreed.

The positioning issues I'm aware of. I assume you designed your forms using the grid layout method.

The validation controls may validate on either the client or server side depending on the browser, this is by design. You should interrogate the "IsValid" property in your form's submit event code before allowing the event code to process. I do agree that the controls should validate on the client for Netscape 4.x, 6.x browsers but at present they do not.
