I have recently upgraded to Avast! Internet Security 9.0 and although for example, I request Firefox to run sandboxed, there is no indication (red line around Firefox window) that it is. The settings has this turned on and Firefox is listed as one of the programs to be sandboxed. Also if I go to Tools/Sandbox, browse and select Firefox to run sandboxed, although Firefox runs there is no program shown running in the Sandbox window.
My computer is running Windows XP Home SP3. I have tried an Avast repair which was recommended and didn't put it right, and also a re-install which again made no difference.
Please can anybody offer a solution for this behaviour?
