I use Chrome as my browser, and I have it set to "always be sandboxed". I un-ticked the top 2 boxes in the "web browsers" settings tab in: additional protection > sandbox > expert settings > web browsers, and I ticked the 3rd box that talks about "not virtualizing all browser settings". All other sandbox settings are default.
When I test the sandbox by downloading Piriform's Speccy, it works as I would expect. It looks like the program is installing, with every box that pops up having a red boarder around it, but as soon as I close Chrome, everything is gone and was never there.
But last night, I went to my online Yahoo mail account and I wanted to watch a known clean to me, Windows Media Player video. I clicked on the attachment, saved it to my desktop and once it was loaded, I clicked open from within Chrome. ( If you are unfamiliar with Chrome, you can't "run" a program like in IE, you have to save it like in FireFox, then chose open. ) I never looked to see if the file was on my desktop. Once I hit open from within Chrome, Windows Media Player opened with no red boarder around it. The video started to play and after 10 seconds, it froze, making a loud screeching sound and totally locked up my machine. I had to kill the machine and do a forced shutdown.
All is fine now, but my question is, shouldn't WMP have opened up with a red boarder around it to show it was within the sandbox? Did my settings cause this? To me, this behavior indicates that the download got through the sandbox.
