I found a bug just now. While I was withdrawing some funds from my HaoBTC account to an external wallet, I interrupted the process (dialog). The status is now showing an 'ERROR', because the funds are withdrawn but not sent. (Waiting indefinitely for support to fix the bug.) That this is even possible is a 'gotcha'. (A correctly functioning wallet should close the bug.)

In the meantime, warning is: do not interrupt or cancel the withdrawal dialog.
