I have a situation in my 1.1 webform where I have a user entering monetary values. I have a RangeValidator set on the textbox with a minimum of 0 and a maximum of 9999.99. Somehow the user is able to enter negative values and make it work. I am unable to reproduce the problem in my testing environment.

Is there some sort of bug with RangeValidator, or a dependency on the user's end that might not exist? This is the second user in a month that this happened to.
