Consider the following code:
<form action="whatever" method="POST"> <input type="hidden" name="foo" value="a very long string" /> <input type="checkbox" name="confirm" /> <input type="submit" /> </form>
In Internet Explorer (confirmed in both 6 and 7) submitting this form with the checkbox ticked results in no response from the server. (Submitting it without the checkbox ticked just brings you back to where you started.) No problem at all in Gecko-spawn or Opera.
Anyone seen anything like that before? And better still, got a solution?
