I've tried to dock three toolbars on the right side of the screen but have not been successful. The CUI is imported from Windows, where it works perfectly. I don't see anything in te CUI file that looks wrong. I've tried the settings in the Toolbar section of the CUI editor without success. What I see is one toolbar that will dock, one that will only show horizontal instead of vertical and will not dock at all, and one the appears to dock but far below the visible screen. Trying to drag toolbars to dock on the sides also does not work well.
My hope is to have identical user interfaces in Windows and Linux Mint.
