I live-updated to the new software/firmware (note the new MX-900/950/1000 manual is included in the update). I then tried to get my MX-900 to "skip" a command by pressing the Info button. I must have pressed it 100 times and it never failed! Before the update it would fail within about 20 presses to register at least one press. Seems like the problem is fixed for me.

What have others found? Can anyone reliably get this new firmware to fail? If so, how?
