Product: Signals Notebook
Blank box with an 'x' when pasting a image in a ChemDraw document
This is a ChemDraw JS limitation. ChemDraw JS does not allow the copy/pasting of images into the reaction box. To include an image from ChemDraw into Signals Notebook, save the document in ChemDraw Desktop as an image file and then use the the Add Content > Image option to uploaded to the experiment.
