I have a little annoyance here. It seems like the sandbox isn’t allways working, when you right-click on the app and choose “Run in sandbox”. Avast 6.0.1000.
Update: I was too fast on creating a thread. It seems like the red outline is gone, but the process is listed as virtualized.
No more questions.
Maybe you can change the topic title according to the problem. And explain under what circumstances the red border is not shown ?
Greetz, Red.
It isn’t shown in cases where i launch applications with their own themes (i don’t know what to call it, but it doesn’t use Windows’ own “windows”). JetAudio for example.
I was unsure about if the sandbox really worked, until i found out that i can check the sandbox page in the antivirus itself, and see the process list.
Interesting 
A little clicking learned me that the red border is indeed not always there. But sometimes by just clicking in the window, or minimizing and maximazing it’s suddenly there. Very strange :-\
But thank you for your report, I will email the Sandbox Developer about it
