Can't save file in dropbox folder

I like to keep my work files in a dropbox folder so they’re always backed up. I tried saving a new map in my dropbox folder but Tiled says “The process cannot access the file because it is being used by another process”. This is brand new file I’m trying to save into the directory. I save files to this dropbox folder all the time from other applications. It works when I unload the dropbox syncing app running in the background, so obviously dropbox is locking the file as soon as it sees it before Tiled can even close the file after saving. That’s my guess at least. Any help would be appreciated

See this GitHub issue for some details about this problem. You can install a snapshot build instead of Tiled 0.18 and de-activate the following option to avoid the problem:
