I've found an strange issue: Everytime I open and save a microsoft office document file (docx, pptx or xlsx) with my Office 2010 tools instaled on PlayOnLinux, the system automatically creates a new file as a .Ink shortcut in the folder where the file exists.

Example, if the document is in /home/user/documents/myfile.docx it will create in the same directory:
myfile.docx (2).ink
myfile.docx (3).ink

I can't understand why is this happening, I've been googling around but found anything regarding this issue, any ideas?
