I have created a new workspace and changed the arrangement of the Modelling Tools palette to single row (see attachment). After I have changed the display resolution of the macbook pro (unplugging the external display) the tool palette pop-up doesn't work anymore. I can only access the visible tools. To me it seems as if the tool groups are lost. However, when I change the workspace to the default one (Modelling) then it works.
I don't want to set up my workspace everytime I change the display resolution. Does anybody else had the same problem and knows of a solution?
