Avast IS 8 Browser Sandbox Issue

hello!

ive got a problem with the current Avast IS version, i just downloaded the installation file for AIS and installed everything (standard installation), after a restart i wanted to test out the sandbox and set up everything correctly to delete all files after my browser is closed after ive used it inside the sandbox. but every time i run firefox or chrome inside the sandbox, the history, cookies, etc. are all there after ive reopened again outside the sandbox … this issue only persists with newer updates, with the downloaded non updated revision (date 07.03.2013) it works just fine and all files are deleted after the browser is closed, with the same settings, no exclusions, no storage option for the browser. is this going to be fixed in the coming versions ? does anyone else have this problem ?
