Bruce,
Thank you for the screenshots. The editor colors do not look normal. Could be a problem with bad defaults in the workspace/system from previous installation.
Is this a new workspace? The fastest way to fix the colors is by switching to a different theme in the Window > Preferences > General > Appearance page.
If you still have problems with the editor colors, then you can try installing DevStyle, our Darkest Dark plugin which provides custom themes for light and dark themes. You can install it from the Eclipse Marketplace or using the update site : https://www.genuitec.com/updates/devstyle/ci/
Once installed, you can choose the theme of your choice from the Window > Preferences > DevStyle > Color Themes page.
Please let us know how it works for you.
