Since installing ZoneAlarm Extreme (previously had internet security which worked fine for downloads) I've found that large file downloads fail at around 10MB with no warning (the ZoneAlarm download screen just disappears). If I uncheck 'Check file downloads for spyware' on the settings page then the file downloads OK - but I'm disabling one of the ZA security features. Has anyone else seen this and found a solution?

Thanks
