There is a weird problem when saving a pdf with PDF-XChange Viewer. When I save it to my local drive it takes reasonable short time. Also if I am in the main office saving to a network drive doesn't take too long, but at least twice the time than onto a local disk. When I am in a branch office, which has reasonable connections to main office, trying to save pdf to a network drive the saving time sky rockets to hours instead of seconds. If I first save it to my hard drive and then copy it to the network drive it takes couple seconds, but directly saving from PDF-XChange to a network drive takes a loong time.

I attached one pdf I have the problem with. Can you explain why PDF-XChange could take so long to save the file if copying a file takes a lot less time?
edit: Okay, so the problem exists only in network folders that are marked as offline available. So when saving to a folder that is synchronized for offline use the saving time sky rockets.
We are using Windows 7 Enterprise 64bit.
