Freeze upon setting graphic export directory

This is a new development. Dorico has been freezing about half the time when I click to choose a directory for graphic export, forcing me to kill the program and relaunch.

It’s happening often enough that it’s really a hindrance; insights appreciated. Thanks.

Dorico (1.1 MB)

Have you made any changes to your system configuration recently? Are you using any network-attached drives that Dorico could be looking for but which have become unavailable?

Thanks. No, no changes. The folder is synced to Dropbox, but it’s always been that way.

As of this morning it’s mysteriously working again. I’ll report back if it happens again.
