I downloaded WS again and rebooted the computer. XP’s extraction wizard still crashed after taking forever. I downloaded IZArc and it worked fine and only took a few seconds. There is something strange with the current WP zip file.
I was going to try WinZip but changed my mind. Then I discovered that WinZip’s setup program can not be exited and keeps the computer from rebooting. I had to power down to get rid of it.
