After double clicking on a structure in PowerPoint 2000, I edit the structure and close ChemDraw to return to PowerPoint, but the structure has not been updated.
ChemDraw 5.0 and lower were developed and released before PowerPoint 2000. Microsoft changed something between PowerPoint 97 and 2000 to cause this editing feature to break. We have resolved the problem in the latest version of ChemDraw. Otherwise, the only solution is to copy and paste between ChemDraw and PowerPoint.
