I have a strange bug with my DBVis 9.9.5 on Macs OS 10.12.3.
I have more tabs open and when I click on a tab, the tabs are switching place :(
This really looks strange.
If you never seen this before, I can try to make a video fit.
This is something we have never heard about before. Do you have any Accessibility apps active (see Security & Privacy in macOS System Preferences) or some other app that may interfere with the macOS GUI?
If not, please post a video.
