STUCK IN THE SANDBOX! and Netflix...

[nb22x]

I use sandbox when I am doing business transactions.
Now it seems like Firefox 12.0 is stuck in sandbox mode. I've tried everything,
from the sandbox menu options in AVAST, turning off auto sandbox,
right clicking the browser icon and asking it to run outside sandbox,
it simply will not run without the sandbox.
I'm running Win XP SP3 and AVAST! 7.
Could this be a virus?
Or an AVAST issue?

Netflix dosen't work for me with the sandbox,
Error code: N8156-6208
Youtube and other videos work though.
Anyone else?

Thanks.

Have you got - Always run this browser selected in the browser protection under additional protection ?

If not, have you tried a repair install under add/remove programs in the control panel ?
