I'm wondering if anyone else here has come across this problem I'm having, I've tried searching already but that didn't return any useful results, so here goes.
I've got an Oxygen 61, hooked up via USB, and Ableton Live 7 running under windows XP. The keys are all picked up by Live, and play notes as you'd expect, and moving all the dials and sliders on the keyboard generates MIDI signals and Live does receive them as that box at the top right lights up when I move them. I can create manual mappings for things using the blue MIDI button up the top right, too.
However, Live's manual talks about Instant Mappings, and not having to configure manual ones for every single panel of every device on every track, but they just don't seem to kick in. When i click a panel (the main one showing the volumes of the 8 instruments in the Impulse drum machine, say) a little blue hand icon appears to say it's being controlled, but moving the dials/sliders does nothing (unless i add a manual mapping

In my options->prefs, under the MIDI Sync tab, I've got the 'Oxygen49 61' listed as the first Control Surface, with 'USB Oxygen 61 In' as the Input and 'USB Oxygen 61 Out' as the Output on that same row. In the lower half I've got 'Track' and 'Remote' turned on for the 'Input: Oxygen49_61 Input (USB Oxygen 61)' line. All this seems to be correct as far as the in-program help files tell me. ('Sync' is just for returning signals to motorised control surfaces, I think)
Am I missing something? I've already tried asking this in Ableton's own forum, but no response, so figured I'd try here too.
Thanks for reading
