I'm noticing that after I apply a starting color correction from bucket 4, which is mapped to F13 I find in the HSL tabs shadows and midtones there are sometimes values other than 100 in the gain parameters.  Also when I go to hue offsets sometimes the cross hairs aren't center.  What's even wierder is that even though the individual track function is active pink there is no effect on the output.  It's been kinda random but happening every 3rd or 4th color correction.  Perhaps the individual parameters are active but the overall tab is not active, I haven't been able to nail down a specific key combo that always does this.  Reapplying the bucket 4 correction usually puts the values back to default.  I just installed a Kennsington Expert Track ball with mouseworks latest intel compatible version.  Anybody else seeing this behavior?  OS is 10.5.6.

Okay now I see the master tabs are not on but even when I turn them on there is
still no effect from the errant values in various parameters. Retyping in the
same errant number has no effect, but typing in a different number has an effect
and then typing back in the original number has an effect. It's like these
dummy numbers are just place holders in the various parameter but not recognized
by the system until the value is changed. Same is true for hue offsets. Even
though the cross hairs are displace from center they are not effecting the
signal until they are reset to center and then moved or dragged from their
errant position. Weird stuff only thing new on the system is the Kennsington
Track Ball with mouseworks and I'm using more tab based keyboard shortcuts.

I also have noticed that when I advance to an uncolor corrected shot it seems like some of the last corrected shots parameters are displayed on the virgin shot.  I'm popping around the timeline using my long time wacom table.  If I then pop to another shot and pop back to the virgin shot the parameters appear to be correct at default.  Perhaps this is where the errant numbers are coming into play.  If I pop to a new shot and the ghost parameters from the previous show are hanging on but inactive that might account for what I'm seeing.  It would also explain why the only parameters that are errant are the ones I typically use for correction.  Hmmmmmmm  This is intermitent behavior but I'd say 30% of the new shots are exhibiting the problem.

I tried uninstalling Mouse Works that came with my Kennsington Track Ball but still the problem.  It now is looking like a display update problem.  Almost like popping a tape in the time code doesn't catch up till you play the tape.  If I go to a tab that has the errant numbers and scrub play or just advance a frame it resets to default.  This can happen in multiple HSL tabs at the same time and each one only updates when it is the active tab and the timeline is moved to a new frame in the shot.  I guess I can just ignore the ghost numbers since they have no effect on the shot until I manually go in and set a value up until then they are just an annoyance.  I just can't see how this has gone unnoticed by me for over 3 weeks on the system.  AFAIK nothing has be updated on the system except my mousework install.  I did install off the disk but that was a non intel compatible version so I uninstalled and downloaded the current driver.  Avid where should I look next?

Today I uninstalled and reinstalled SNDX but still the problem exists.  I have now localized it to when I switch tabs using a keyboard shortcut.  For example go to a new shot apply my default correction and hit the key for hue offsets and the cross hairs are not centered.  Use keyboard shortcut to go to another tab and then use the wacom pen to select hue offsets on the screen and voila the cross hairs are centered.  There must be some bit of code that is not invoked when using keyboard shortcuts to get to tabs in the Color Corrector that doesn't tell the GUI to update to the current shot.  This seems to be where the problem is cropping up.  This explains why I wasn't seeing this until I started using the track ball.  At the same time I started using keyboard shortcuts to get to the various tabs in the color corrector and that's when I noticed the problem.  Can anybody confirm or deny this behavior on another Mac or PC system?
