Bug Corner

Due to a JavaScript super-bug, on some platforms the last radio bottom - beg your pardon - button, on a form cannot be turned OFF on the screen. So the fact that you see it ON does not mean that it is ON computationally. To check whether or not your platform is infected

This should turn OFF all the radio buttons.

If you machine is infected, do the following:

  1. Clear the radio buttons by clicking the CL buttons, and ignore the button that remains on (JavaScript bug!).
  2. Click any one of the radio buttons.
  3. Write a letter to Netscape and/or whoever sold you your browser.
