Running MC 2.8.3 on OS 10.4.11.  Having odd color correction issue.  Place my position bar on the clip I want to effect (making sure that track is highlighted), then open up color correction tool and start altering parameters, unrendered CC icon pops up on my clip in the timeline, but as I make the change it doesn't seem to be effecting composer image in anyway.  So effect isn't showing real time as I make the change, as I play the sequence, or after I render.  What am I doing wrong?  Nick.

Hi,

Under the Special menu, make sure Render On The Fly is checked.

good luck,
Carl 

Many thanks, that did the trick.  Nick.
