iweb

I'm running Parallels 16 on MacOS Catalina with a Yosemite guest OS to use iWeb. When I open iWeb the windows do not render correctly. At first look they appear blank but some of the page content appears to be placed outside of the window borders. How can I get the pages to render correctly?

I'm about to upgrade to Catalina and am considering running Mojave on Parallels to use my few legacy apps. The one app I cannot live without is iWeb. Has anyone run that using Parallels/Mojave on Catalina? If so, could you give me some feedback - does it have all the functionality, fonts...

I have been trying to run iWeb in Mojave, which is installed in Parallels (15) Catalina. The screens are blank white. What is the problem?
