Thanks for the heads-up on Mintpal guys.
I just woke up after a fitful 1 hour of sleep - maybe my subconscious was telling me something.
I managed to withdraw from Mintpal and funds are now in my wallet.
I may not use them again what with the silly trade patterns previously reported in this thread and now this fiasco.
Looks like all current orders are locked and cannot be cancelled
