Sorry, I presumed this was about the Limit Order/Stops issue, that seems to be largely a WHC problem. If you are talking about not being able to place stops simultaneously with market orders, well, this appears entirely reasonable to me - there is no way of knowing what the exact eventual price will be prior to placing your order ('cos of slippage, delays in order processing etc.) and as stops are meant to be 'absolute values', this would require the broker having to alter you stops in the event of slippage...
