Just installed version 28 and it is crashing. I'm preparing to uninstall/reboot/reinstall it. The first step is to backup the Library. My Library is in a folder that is sync'd with Dropbox cloud. (I do this as a convenient way to always have a backup of the latest changes on the cloud and to get to prior versions if it were ever necessary).
I selected a different sub-folder in my Dropbox folder to put the MC backup ZIP file, but when I do File>Library>Backup Library I get the "Library Backup Failed" message, though there is ZIP file there. I tried again, this time using a folder on the same drive but not in Dropbox, and got no error message.
Can anyone explain why the Backup Library function has a beef with Dropbox? It makes me concerned about using MC with the Main Library in Dropbox. The MC app itself is on another drive in the same Windows PC. I don't see any need to back that up because I can always just reinstall it.
