This (the below) has all occurred from a single operation in which I created three colored tabs, all in the same window, then deleted them.
– I created three colored tabs in a window just to see what they looked like. (First time using them.)
– After removing them completely in the window in which I’d created them, I found that colored tabs were appearing in other windows.
– That’s still continuing to happen. Colored tabs are showing up seemingly randomly.
Is there a ‘reset’ for this so that I can stop it from happening?
