I was able to fix this -- you have to uninstall (reboot) and then re-install dropbox. That re-installed all the permission stuff and got it working. Sadly there is no 'repair' option and I just went right for uninstall/reinstall.

Hi danens1863,
I agree with you, that many new "features" of Dropbox look like bugs. According your description, seems you are disturbing by a bug with name "Smart Sync". Very poorly implemented and as a result such issues come up. If you can, turn this feature (bug) off. If you need to save disk space, considered "Selective Sync". As a last resort (you can't live without "Smart Sync") make sure the files you are working on are set 'local' in advance. 🤷 That's all you can do with Dropbox right now.
Good luck.

To make sure that I can open an online only file I have to first set it to be "Make Available Offline". The type of files affected were JPG's and Zip's - compressed data.
