I've been away for a while, but before I went I updated to 7.0.1474 without any problems. Now when I try to run Firefox (17.0.1) in the Sandbox I either get no browser appearing (even though AIS says process is running sandboxed) or more commonly I get an endless (>10 and continuing) stream of "Data Execution Prevention" popup windows (themselves sandboxed). Only way to stop them accumulating appears to be to hit the "terminate all" button in the AIS Sandbox window.
All runs fine when not sandboxed. Any thoughts on a possible cause? I've cleared the Sandbox cache and rebooted but nothing changed. Should I try an AIS repair?
Still running XP.
Thanks
