Folders re-opening: unwanted behaviour

[Crank]

Hi and help please.
This has been going on for a while and I haven't been able to find a solution.

When using folder tracks I can close a folder from the console but often my session gets in a state where a previously opened folder automatically opens without me touching anything. This happens every time I open any other folder.

It happens with or without Automatic Spill of Attentioned Folder. It also happens when I close a folder from ProTools. It happens whether or not the folder that is automatically re-opening is attentioned or selected. Closing folders with the Transport Module Soft Keys doesn't stop the behaviour.

I have noticed that while this behaviour is happening the M10 shows "Please wait.. Loading Session Data..." every time I close a folder. Then the other folder opens again (on the surface and in ProTools).

The session will work as expected for a while then this behaviour starts and I can't stop it. It happens in every session using folders, small or big.

Re-starting ProTools doesn't fix it. Power cycling the M10 doesn't fix it either.

Has anyone else experienced this?

Any help will be greatly appreciated.
