OblyTile works very well for me, however there is one problem I am running into and I wonder if anyone can help?

I want the start menu tiles to return to a program which has already been opened (when applicable), rather than opening a new window. As far as I can tell, this is where the single instance option is used. It works well enough with chrome etc., but with MS Office applications it will always open a new window, even though the original Office tiles did return to the original window.

Is there any way resolve this? Has anyone else had a similar issue?
