fails with Live 9.6.1 and Max 7.2.3

[mzero]

With Live 9.6.1 and Max 7.2.3. and it doesn't work: The LP Pro shows the right lights when I go to User mode.... (the yellow 4x4 grid, the clip lights on the right, etc...) but pressing any buttons does nothing.

Opening up the patch in Max, and looking at the console I see this:

get: no valid object set
get: no valid object set
method pushcontextframe called on invalid object
method popcontextframe called on invalid object

The last two messages are repeated every time I press a pad. I'm not good enough with Max to know how to track this down.
