All the applet tools on MathPad was designed to be used as a quick popup calculator on Web browser.(likes Internet Explorer, Netscape Navigator, etc.)
All the applets do not communicate with serve machines after being loaded on each client computers. so you can use the applet continuously after loading it once on your computer, even when you computer is off line.
If you can't see the whole applet window (you can see only MathPad title located on upper-right corner of window), you have to upgrade your Web browser to new version of it. It's the problem related to bugs of java virtual machine embedded in older version of Internet Explorer or Netscape Navigator.
