"This does not really strike me as a browser issue, I think that you and et viola have hit the nail on the head when you both suggested "buggy installation" and "reformatting the HD".

I would guess, after reformatting the HD, when installing each individual app it should be checked that it works before moving onto installing the next app. That way each app and problem can be monitored, isolated and if necessary dealt with."
