If I hit "save" on a chemdraw document, the first time, the document isn't saved, and if I do it a second time, chemdraw crashes and does not save my document. Anybody else experiencing this problem? It was working fine yesterday. Overall performance is sluggish.
Chemdraw 16.0
Mac OS Sierra, 10.12.1
macbook Pro, Retina 13", Early 2015
2.7 GHz Intel Core i5, 8GB RAM
