strange monitoring issue

i've been having a strange issue with monitoring in pt 11..



when i disarm a track, i can still hear it through the speakers. i can even delete the track and, as long as the microphone (or anything: instruments, etc) is plugged into the interface, you can still hear it. in fact, i can have a completely blank session and i'll still hear anything that's plugged into the interface.

to remedy this, i've just been doing all tracking in pt 10 (which does NOT have that issue) then switching to pt 11 for editing, mixing. this should not be happening though.

has anyone else had this issue? i'm lost as to how to fix it.



the interface i'm using is irrelevant as it's done it with 3 different interfaces including what i'm currently using which is an apollo twin duo.

at first, i was using the mbox 2 pro so i assumed that antiquated, unsupported hardware was the problem. i got the apollo to remedy the situation (and just as a cool upgrade) but the issue didn't go away.



any ideas i haven't tried are welcome BUT, more than anything, i'm looking for someone who has ACTUALLY EXPERIENCED THIS and REMEDIED IT!

thanks!!!
