Internet explorer. A custom CMS. And sometimes some of the posted data is missing... On a single POS. And because data ath end of form is optional, system can't even figure out that something went wrong, it just silently discards it. Never figured out what problems that particular IE had, but the workaround was simple... I added an extra hidden input field just to check if all was sent. The theory was that at least operator could repost the form if it went wrong - however, it never did again. Thank you IE for your obscure bugs and nonstandard behaviour! Rip. </rant>
