Some of these ads actually crash Internet Explorer on Windows ("this application has performed an illegal operation and will be shut down"). The workaround? Right-click on the Internet Explorer icon and choose Properties -or- from an IE window, select Internet Options... from the Tools menu. Click the Security tab. Then click the Restricted sites icon. ("This zone contains Web sites that could potentially damage your computer or data.") Click the Sites... button. Under Add this Web site to the zone:, type http://oascentral.cybereps.com and click the OK button. This stops the crashing and speeds things up considerably.
