Trying to either drag or option drag sequences from one bin to another won't work occasionally. Have to restart the app and do it again. I have experienced this both on 3.0 and 3.0.1.

And your complete system specs would be ..................... ??

I've had it happen on my macbrook pro using 3.0/Leapard 10.5.3/2.0 G RAM and happened on a rented Adrenaline Avid 3.0.1 with Tiger. Don't have the complete specs on that as I rented for a job out of town and now am back. Basically I try dragging a sequence (didn't try anything but) and it just snaps back to the original bin. I restart MC and that fixes it. It happens intermittently, so it's a tough one to pin down. At least for me. And it's an easy fix, just wondering if anyone else have this happen.

We just installed two MC Nitrix DX's and we'll keep an eye out for it there when we start working on them.
