Alright, first some set-up information: 2.8GHZ / 4GB RAM unibody MBP hooked up to 20" ACD in clamshell mode (closed lid) apple BT keyboard and mighty mouse the apps i've had this happen in, are: ableton live (full-screen mode) and awaken (with full-screen wake) so i assume this is limited to full-screen apps only. this doesn't always happen but when it does, it happens at a random time (what i mean: sometimes it happens after 5 minutes in full-screen mode, sometimes after an hour of two) my system continues to run just fine, the only problem is, it just ignores any input. the BT mouse and keyboard just become unresponsive, even though they are paired and running. when i open the lid and use the track pad, this is being ignored as well (doesn't even show the cursor) then, when i take the MBP out of my self-constructed 'dock' and open it, i can see a cursor, but it's still unresponsive. it doesn't matter where i click, there's just no reaction. just to be clear on the symptoms: my system does not freeze! the track i was working on in ableton just keeps on playing and everything works accordingly, my input is just no longer accepted. does anyone know what this problem is exactly and how to solve it? it's rreeaallyy annoying.
