3ds max 2022.3
Corona 7 Released on Jul 21st 2021 (hotfix on Aug 12th 2021)
When I start render, and switch to another window, render is actually not starting. It stays on "Parsing Scene" phase. It doesn't start until I switch back to 3ds max window.
When I switch to 3ds max, and make it active, it is immediately starting "Parsing scene" and render well.
