While the Dropbox app is running, when i saving a word document as a pdf in a folder on my NAS and select the "open file after publishing" option, the pdf file will not be saved successfully. If I don't select the "open file after publishing" option, the pdf file will be saved successfully.
It only happens in the folder on NAS. And close the Dropbox app will solve the problem. Saving as a pdf in a local folder doesn't have this problem no matter the Dropbox app is running or not.
And the Dropbox sync folder is a local folder. It doesn't have connections with my NAS.
