Questions about SbieSvc.exe and 'run sandboxed' issue

Hi,

 

I've just installed the latest version of SB under my Windows10.

1.I closed SB from the system tray but I noticed that I have 2 SbieSvc process running. Is this usual ? Why not only one process ?

2.When I right-click on a word document to 'run sandboxed'. SB opened Word but not the file. I have to open manually from Word program itself.

PS: My Word version is old, Word2007.

 

Thanks in advance.
