Dropbox Sync Results in 0-Byte Files

Hey All,

I have a ReadyNAS 628X, with F/W 6.10.5 Hotfix 1 -- we just switched on bidrectional dropbox syncing and have an odd problem.

Files copied directly to the Dropbox directory sync OK back to the NAS, but files copied to the NAS directory sync back to Dropbox as a zero-byte file. Has anyone seen this happen, what are the possible causes and how can I fix this?

Thanks,

Anthony
