Video preview-out is one step behind my selection

Hey all,

Colorist here who is new to using Color professionally. Our house finally upgraded to Studio 2 and while I've been using Color at home for months now - my work set up is a little different.

Just started grading my first project and I noticed that the video preview out lags one step behind whatever I'm doing in Color. This only happens on my video preview monitor - the UI window/monitor attached to my computer updates live.

Is there a setting that I'm missing or a fix for this?

I have a Mac Pro Intel machine with a Kona 3 card from Aja - all the latest drivers (5.11 or 5.1 NDD I believe.. whatever their latest version is). Also still running Tiger 10.4.11 and Quicktime 7.4.5. Color is version 1.0.2.

So an example is I disable a secondary grade but my video preview doesn't update that. Then, if I enable that grade, the grade looks disabled on my monitor - like it's always one step behind what I'm actually doing. This forces be to make a change and advance a frame (arrow right) which is highly annoying. Surely someone has a solution for me, yeah? I hope so.

Thanks a lot.
