It sounds like that particular stereo was routed to a multi-channel path because, according to the documentation…

Multichannel Panner Linking

Stereo tracks with multichannel outputs provide
left and right multichannel panners. The Output
window provides controls to link the left and
right channels for precise panning.

When you create a stereo track that is routed to
a multichannel output, the following pan link- age
controls are active by default:

• Link (links Left and Right pan controls)

• Front Inverse (inverts Left and Right pan
control linkage across front)

• Rear Inverse (inverts Left and Right pan
control linkage across rear)

The Front/Rear Inverse pan control is unlinked
by default.

The same information also appears in the “What’s New In HD 7.4” document (Chapter 3: Miscellaneous Pro Tools Features and Enhancements; pg. 49).

IHTH.

aha - cool - thanks!

I suspected this to be the case..... right at the beginning....

initially when i thought this was the issue, I assigned the output of the track to a stereo path - but the link stayed - i guess it doesn't 'unlink' once it is linked.....

interesting....

thanks!!!
