When I open a document from SharePoint library using Visio 2010/2007 API (Documents.Open),
Documents.Open "http://mysharepointsite.com/Diagrams/MyVisioDiagram.vdw"
Visio downloads the same file from the SharePoint 3 (!) times for some reason:

When I open document using UI (File -> Open), Visio reads the file only once.
(http://dl.dropbox.com/u/82866570/12-02-2013%2017-39-16.png)
It seems that no such issue exist with Visio 2013 (file is always read once)..
Maybe I am missing something here (or have some configuration/security issue in SharePoint)?
Why Visio downloads drawing data 3 times when called from API and is there a way to avoid that?
Thank you in advance!
