Ever since Microsoft downloaded its latest upgrade, Netscape won't work right.
About once every two minutes, Netscape suddenly freezes. Other functions on the screen (such as the taskbar, and other software) continue to work. This lasts a minute, and then operation resumes for another minute.
I opened the task manager and selected processes. During the frozen minute, it shows Netscape consuming 99 percent of CPU time.
Virus scans show clean, and spyware scans show only the usual junk my ISP puts there.
