Midisport usb drivers not crashing Sonar 7

In past Sonar versions, Sonar would eventually lose midi function. I would have to save and usually reboot and Sonar would hang up computer shutdown even when not showing up in the task manager. This made for a rather prolonged reboot and was an annoyance I had figured I would have to put up with in perpetuity. The conventional wisdom is that the M-Audio midisport midi interface drivers are the culprit and since M-audio did not ackowledge the problem and were not inclined to look into it, that was that. Well, _SO FAR_ this has not happened in Sonar 7. I'm keeping my fingers crossed.
