Ableton rewired into Sonar giltch

[higskies]

Has anyone encountered a problem with Ableton rewired into Sonar like this:

I can play the instruments via a controller when I have the Sonar screen on the computer monitor, but if I change it over to the Ableton window, it 'holds' the notes until I switch back to Sonar. As in, when I switch over, the notes I played before, all sound out at once, like I opened a 'trap door' that was holding them back. I don't know if anyone has had this issue, or what steps I could take to correct it. Both programs work fine independently of each other, it's only when I rewire Ableton.
