One suggestion - use trailing stops on open orders. if you get one that won't close, set the trailing stop as close as the broker will allow and then see if you can insert a TP order as close as possible.
In the meantime, I hope Alpari steps in and tries to fix the issue.
Thanks very much for your suggestions, Pharaoh.
I did end up using TP to close some orders, but not Trailing stops. Good suggestion.
Nevertheless, the few seconds spent in manually setting up the TP or Trailing stops would inevitably also lead to loss of some pips,
and I may have to repeat the setup process if, just before I click the button, the price move past the minimum pip difference allowed for TP or Trailing stops.
