Avast Browser Sandbox automatically deleted do not work!

Hey there I just upgraded my Avast from 6 to 7 withit the built in updater and had no problem with my settings until I upgraded it to 7. I like to browse the internet sandboxed with avast and when i close it everything should be removed and nothing is saved not even the history, coockie , files bascially everything gone when I close the browser, and I like that. But when I do the same thing with the same settings in avast 7 it doesnt remove it, the history and coockie and everything is still there, even tho I have the same settings as previous version, I dont have that cache on or other settings, only the “save downloaded files outside sandbox”, rest is off. I think there is some bug there, can you guys please check it out.

Or add maybe some feature that lets me remove everything on browser exit.

Avast rox!

bump…

Is there no developers visit this site that can answer this.
Search history is retained even when clearing the sandbox which is a serious bug
