Hi, I have a really frustrating problem that has stumped even our I.T. department at work... I'm not sure this is the correct place to post this (apologies if so) but I'm hoping someone knows the reasoning behind it or has had the same issue...

My old laptop was installed with Office 2013. I could open 2x files from any location on our SharePoint and they would open in the same application of Excel, and therefore a simple = formula in one sheet, could be linked to the other with a simple click.

My new laptop is also installed with Office 2013, but now when I open up two Excel files (even from within the same SharePoint location) they are in seperate applications, and the linking process doesn't work. The only way I have now to make it work, is to go into the first file, and go to File>Open and in through the folder library rather than through the browser links. This is not a workable solution for me...

I can however open up two files from my documents saved directly on my harddrive, or choose one file from my documents, and one from SharePoint - either of these two options opens up the files in the same application.

So my question is this - what could have changed to suddenly prevent my ability to open these files in the same application? I've been through all the settings in Excel and nothing stands out to be the culprit.

Any help or assistance would be brilliant, as my I.T. support are shrugging their shoulders and doubting it ever worked the way I've described in the first place...
