I haven't done anything other than add my footage to the timeline. I have 2 layers (1 targa seq and 1 png seq). As I move my mouse from the Timeline to the Comp Panel, the color values flash for a split second and go away. If I press Opt+1 (2, 3, and 4) the Info Panel displays the color for that one pixel but the values go blank as soon as I move my mouse. This happens in the Comp Panel mostly. If I open a Footage or Layer Panel, sometimes the values show, sometimes not. Never had this issue in previous versions.
The issue seems to be with the .tga sequence. If I turn the .tga sequence off, the color values appear in the info panel for my .png sequence. With the .tga on, I get no color values for either (.tga has an alpha channel). I've never had issues with .tga's in the past.
