Operating system: Windows  
Slicer version: 4.10  
Expected behaviour: Manual segmentation  
Actual behavior:  
Hi there, whenever I use the paint effect and paint the area of interest on the current slice, I find some an automatic painting effect on the next slice. this problem came up after updating to the latest release! What shall I do to get rid of this problem? I want to do manual segmentation, one by one! please see the attached photo for more clarification.

This is normal when you paint on oblique slices. Click the button with the warning sign (next to the segmentation node selector) to snap all slice viewers to nearest segmentation node axis.
