Hello Everyone, I have had this problem with ChemDraw for a few years now and now that I am stuck working at home on a laptop (COVID), I need to address it. When I open ChemDraw it will open fine and I can start woring in it. However, it will then start to attempt to open multiple other ChemDraw applicaitons (literally the same program). They will just keep bouncing in my 'Task Bar' while I am working in the window I orignally opened. I will regululary have three different ChemDraw 'applications' showing up in my task bar (see image below). I just ignored it for a long time, but now it is consuming a large amount of CPUs and dragging down my laptop. Can someone help me!

OS: 10.15.4


Thanks for any help in advance!

ChemDraw 18.0 not compatible with Mac OSX 10.15.

Our current version products (v19.0) supported with Mac OSX Catalina (v19.0 qualified with Mac OSX Catalina Beta), so we recommend to retest with v19.0.
