Common to all browsers: Some analysis types will run slow, so please be patient. The computations performed by F A N T C can be extensive. Please run a few demo's to get a feel for how FANTC works.

• IE browser versions 4.x through 6: Slow script warning (normal). If alerted, allow script to continue. IE6 is the fastest browser tested.
• Netscape browser versions 4.x Although no warnings have been identified, a slow script warning may occur on some systems. If alerted, allow the script to continue. Slower than IE6 or NS7.
• Netscape browser version 6: ANALYSIS RUNS VERY S L O W. Recommend running F A N T C using another browser type or version. Slow script warning (normal). If alerted, allow the script to continue. Slowest browser tested.
• Netscape browser version 7: Slow script warning (normal). If alerted, allow the script to continue. Applet used to draw system does not work in browser version. This is currently being looked into. Faster than other NS browsers, but slower than IE6.
