A drawing disappears after Cropping Volume

Hello,
I try to segment femoral cartilage. To do so, firstly I crop volume containing the area and then try to segment the cartilage using “Draw”. The problem is that I’m unable to do it - it disappears. A painting option works - it marks the area.
Could you help me?

This could happen when the slice view is positioned right at the boundary between two slices. This is not likely to happen if you use latest Slicer Preview Release. If you the issue is not resolved then let us know and we can give further advice.
