After some time after a new installation the symbols/icons on the right in the "Swatches" and "Layers"-windows disappear. In the layers-window I can no longer move elements in my document from one layer to another by using the small colored squares - an option I use very often. Furthermore you can see in my screenshot that there are options-icons missing on the bottom of the Color-Swatches ("Farbfelder") window. For example the recycle bin.
The only solution I found until now is reinstalling InDesign CC. But that's not very comfortable.
Does anyone know how to turn those symbols/icons on again without reinstalling.
