In this latest release, the following bugs have been fixed:

On Windows, the pasted structures can be opened and edited in ChemDraw Desktop if it is installed. It is also now possible to copy images from ChemDraw JS 17.1 into Microsoft Office documents and back into the ChemDraw JS canvas.
  • Compounds Exact Mass calculation: Exact mass can now be calculated when drawing a structure as a Chemical or in a reaction scheme.
  • The hotspot disappears when drawing molecules in Signals Notebook.
  • Shift+K sprouts a dimethyl group instead of tert-butyl group on primary carbon atom when molecule drawn with CH3 label.
  • The hotkey “k” does not sprout sulfonyl group for certain molecules.
