Preferences chance automatically within session

[Brave Noise]

Hi I've got a rather strange issue on my system.
while working on a session, having "timeline insertion follows playback" and "edit insertion follows scrubb/shuttle" disabled in the preferences, these preferences chance spontaniously after a while.
Has anyone every experienced this same problem?
I've tried installing a fresh copy of DAE, Protools software and thew away all prefs, but still is doing that.

My set up:

G4 500,
Mix plus, plus an extra Mix farm,
Magma expension chasis,
Atto SCSI card,
Protools 5.1.1.
Firewire backup drive with retrospect software.

It drives me nuts and I can't think of any solution. Could it be firewire. I've experienced strange things before with firewire

Spark,
It happens to me every other session. I don't remember where I read it but hitting the "n" key on your keyboard will toggle that function. So of course when I'm throwing my hand at the spacebar.... you get the idea.

ha! this is an old one. Still gets me. Silly place for that function. We need to aim better for that space bar!

Thanks for the replies, It's driving me nuts. I better keep an eye on my big thumbs when hitting the space bar, ahhaa.
