I've had to support this problem a few times, Ken.
To date (yesterday) my solution was to ask the user to click on the very extreme bottom edge of the Bank Genie screen and drag it down a little. By magic, the Menu bar normally appeared.
That didn't work in our telephone session yesterday, so I am very pleased you found this information.
Its much easier and far less haphazard than my previous "solution".
Many thanks for posting. I shall add it to the Bank Genie User Guide FAQ
PS:
Members may be interested to know that it works for any application. There are more options on that Shortcut menu which appears.
