Regular Expression Validation Question

[Jon Natwick]

I am using the following script to validate e-mail address format. The
problem I'm having however is that if I enter a long invalid string, like
"123456789012345678901234567890", CPU process for this process goes to
maximum and IE does not respond.

I am doing something wrong or is this a bug? Is there a way I could prevent
this behavior?

<asp:regularexpressionvalidator id="vld1EmailName" runat="server"
ControlToValidate="tbEmailName"
ValidationExpression="^[A-Za-z0-9](([_\.\-]?[a-zA-Z0-9]+)*)@([A-Za-z0-9]+)(([\.\-]?[a-zA-Z0-9]+)*)\.([A-Za-z]{2,})$"
Display="Dynamic" CssClass="ValidationMessage">E-mail format is not
valid<br></asp:regularexpressionvalidator>

There is a similar posting that came up a few days ago. From the best
of my understanding it might be a bug in IE's javascript regex that
appeared sometime in the latest SP2 update.

Thanks for reply!

That makes sense as I am using Ie 6 Sp2.
