Is there a difference between stand-alone Tk and the Tk plugin?
Yes. While regular Tk and the Tk plugin (http://tcl.ActiveState.com/software/plugin/) are based off the same source code, the plugin is subtly different due to its web-based interaction. Primarily, the security policies for the plugin remove certain commands from being evaluated in the interpreter (the plugin code is run in a safe interpreter). Also, there are some enhancements to the plugin (as of v2 of the plugin) such as the ability to intercommunicate with other applets or other sites when being run. The plugin works with Netscape 3.0+ or Microsoft Explorer 3.0+ for Unix, Mac or Windows.
