Color correction settings problem

Hello,

I'm using avid xpress pro. I'm not yet used to it. I looked up in the help section but found nothing that could solve my problem.

My color correction tool is not working properly. It used to worked fine but now I can't get any of the scope, RGB and waveform monitors in the previous and next window. It just shows me the current segment in the three windows.

When I make some color correction, it dosen't apply on the segment. Sometimes it does, but I can see the changes only if I press the play button.

The green button of the real-time is on.

I would appreciate some tips

Thank you very much,

M Savignac
