I need to disable syncing in order to save changes in Photoshop.

Thanks Mattias3 - Seems we are in the boat.

Not sure about you but I changed nothing at all about my setup, as in my daily workflow/methods - the only thing I can think of is maybe the latest Adobe PS install is bad, or the latest Dropbox update is bad, - both of those are the only things that I can think have actually changed of late.

But saying that I was using both fine until a couple of weeks ago, 

One thing I do notice is that Dropbox estimates for upload speeds and times are massively out, and fluctuate madly between huge and small numbers.

Yes - Please do!

Im having the same issue.

Yes - I am sure I answered yes to this already but I have heard noting - this is really becoming a pain in the A$$ 

Are you able to replicate the problem?
Do you need any more details from me?

The only thing that may change soon is I will have to updated to Windows 10 within next few days - if anything changes then I will report back

Not solved for me. Impossible to save a Photoshop file while the file is being synced by Dropbox.

This issue is driving me insane. I work with large files all day. The previous functionality of Dropbox was simply perfect, I could save a file any time, and it would restart syncing when the file changed. Now Dropbox locks the file and I can't save the file again until it's finished, or if I pause Dropbox, click save, then unpause Dropbox. I work with 500MB files routinely in Blender and Photoshop, waiting for syncing to finish isn't an option, and pausing/unpausing Dropbox every 5 minutes is driving me up the wall. If this behaviour isn't reverted back soon I will have no choice but to stop using Dropbox as this issue is now distracting me from my work. Dropbox should be something I can ignore, that runs in the background, not something I have to micromanage every 5 minutes!

Hi, This issue needs to be fixed. Walter you are welcome to make a test on my computer. In my case it is not Photoshop, but an app for flow analysis. If I try to compile a project with Dropbox active, it fails. But if I put Dropbox sync on "pause" it works smoothly. So Dropbox is interfering with something it shouldn't. During compilation a temp file is created, and I think Dropbox put a lock on this file, and thus interupting the process.

Hi All; apologies for the late reply.

I was just wondering if any of you are still seeing this behavior when editing files that are syncing via our desktop app through a 3rd party app. 

If you do, I'd like to put you in touch with our support team so let me know here and I'll create a ticket for you asap using the email address that's linked to your profile(s) here on our Community.

Thanks a bunch for your patience and cooperation and I'm sorry if this has caused any inconvenience so far. 

HI - many apologies, I swear I replied to this with an update - anyway, will try again.

After finally intalling Windoiws 10, the problem has 95% gone, I can now save files in photoshop without error and without having to pause sync.

The only error I see now, with regard to sync and Adobe, is when I am in Bridge and I am updating Metadata on my image sets. Some will fail and not save the changes, but, if I turn off Dropbox sync they will all update no problem.

So, in short, yes, seems sorted but I assume due to windows 10 update and nothing that Dropbox did, anyway, we should all be on Win 10 now anyway (yay!!!**###???), also, if you are on Win 7 - you can srtill get the free update, if thats what holding you back
