Internet Explorer 11 application errors while using sandbox.

I receive application errors while browsing in the avast sandbox.

A majority of the errors occur while trying to watch youtube videos and other times just random errors occur (meaning, I have no clue what just happened).

Firefox, sandboxed, just quit working while trying to attach the images to this topic.

The virtualized process list now remains after rebooting.

Using IE11, Windows 8.1 x64

I submitted a ticket while using 2014.9.0.2013 and was told to install the beta to see if it fixes the problem so here I am.

Still here in 2014.9.0.2015
