MOST features of the C4 Project website require Chime, a Netscape Navigator plug-in which renders 2D and 3D molecular structures within a web browser. Chime is only compatible with more recent versions of Navigator. It is not currently 100% compatible with Microsoft Internet Explorer. For the latest information on Chime versions and browser compatibility, visit MDL Information Services, the developers of Chime. Chime and the recommended Netscape browser for using it can be downloaded by following the links below. Chime is currently supported for MacOS PowerPC and Windows 95/98/NT platforms. Earlier versions of Chime, which will work with some C4 tutorials are available for Windows 3.1, MacOS 68k, and SGI Irix platforms.

			Chime: Required to view any C4 tutorials. Version 1.0 or later required, 2.0 recommended (2.0a for Macintosh).
		Netscape Navigator 4.06 (or later): Browser recommended for use with Chime 2.0 on all platforms.
		Netscape Navigator 3.04: Browser recommended to use with Chime 1.0 on Macintosh.

After downloading Chime, we recommend that you check out our Chime Tutorial.
