Yes, change the driver. ASIO DirectX full duplex bollox is completely worthless and you should never use it for reasons you have already found out. Download the official ASIO driver from M-Audio for your fasttrack, or download ASIO4all which will probably work as well.
edit: sorry, I see I didn’t put that down very politely. I hope you get the point
Very happy to report that it’s problem solved. Computer safe from ejection-from-property-via-window.
Thanks very much for that. Didn’t really consider the ASIO DirectX to be a potential cause until I typed it. DirectX… reminds me of shoddy plug-ins from the SX era of Cubase…
