Copying bitmaps issue after updates

I had been working with an older non-cloud version of Photoshop CS5 and Fontlab Studio 5.1.2 on an iMac with El Capitan for the last few years. Just this week I updated to Fontlab 5.1.6 and updated my OS to Sierra OS 10.12.6. I just discovered that I can no longer copy and paste between Photoshop and Fontlab or from Fontlab to Photoshop. 

Any ideas what is causing this issue?
