I am running Netscape 7.2 on a Windows 7 - 64 bit OS. When I open any link to a page with dynamic content, I receive an error window from the Shockwave Flash plugin, saying that the plugin performed an illegal operation, following which the system locks up. For example, the problem will occur if I go to the Adobe page that dynamically displays the installed Shockwave Flash plugin version. The Netscape program has been operating for a long time without this problem, so it must be something that I did recently. Any suggestion on how to solve this will be appreciated.
