Insert Color - drop down not working

The Insert Color drop down doesn’t seem to be working in Mac 11.1 Xojo 2020 r2.1. The color picker appears but double clicking a color doesn’t return to the Xojo IDE. Anyone else have this problem?

Further testing show it needs to select the colour then close the color picker with the close button - 2 steps rather than one.
