I am using Groupy Version 1.41 and DisplayFusion Pro 9.7.1 (Beta 4).
This only happens when the windows are in a group.
It only happens when in full screen mode.
Your asking me the question of "Also are you using always on top tabs, or combine mode tabs?" has actually cured the problem. I never thought of trying the 'Combine if possible' because I liked having the active tab in a bright green to make it stand out.
The 'Combine if possible' doesn't let me change the colour of the tabs. Is there a way in the 'Combine if possible' mode to change the colour of the tabs?
Thank You for the info.
