Hi,

I am using Slicer version 4.11.0-2020-06-06 and not able to adjust the contrast and brightness for images using the mouse pad. I was able to do this on Slicer 4.10.2. How can I fix this?

Thanks,

Vinny

Window/level interaction has been changed in 4.11, see: [Recent improvements in window/level management](https://discourse.slicer.org/t/recent-improvements-in-window-level-management/7284)
