While opening a file from Projectwise, it is "receiving changes" for reference files that were not updated in a while. Why?

Hello,

I run PW 10.00.01.28. I have noticed this issue that happens once in a while. It is better explained with a example.

Consider file VBWorking.dgn. The very first time I had to open this file, Projectwise took a while to open it  - I understand this is because it has to download all the reference files attached to VBWorking.dgn to my local drive. Lets say I have been working on this file everyday for 22 days now. On day 23, I open VBWorking.dgn and it is taking a while to get past the window that says "Receiving changes for xyz.dgn (1/50)...". It goes on to receive changes for all of the 50 reference files attached to it. And instead of just receiving changes, I believe it might be trying to re-download the entire reference file.

I am quite sure that not all of the 50 reference files attached to it have been revised since the last time file VBWorking.dgn was opened. I am also sure that the reference files previously downloaded to my local drive were not deleted. I do not understand why Projectwise is trying to receive changes that were not made in the first place.

This is not such a major issue when I am working in the office and directly conencted to the company network - the dgn will load up in 5 minutes or so. However, it becomes a "work stoppage" issue when I am working remotely and connected to the company network via a VPN. The files are stuck forever in the "receiving changes" mode because these are large reference files. Internet connection speeds play a role - I understand.  But this issue, in my opinion, can be avoided if PW doesn't try to "receive changes" for reference files that were not updated at all. 

Am I doing something incorrectly and causing this issue? Could you please explain if this is normal? 

Please see the attached screenshot for reference. Thanks,

Vinod
