Any page that uses the ChemDraw Plugin locks up and freezes my computer.
Most likely you have installed Windows XP, SP2, which now has extra security that may cause this problem. Set up CambridgeSoft as a trusted source in Internet Explorer. From the Tools menu in IE, choose Internet Options, click on the Security tab, then the Trusted Sources option and set up any cambridgesoft.com sites you intend to access. Quit IE, launch IE and retest.
