Hello there Scott!   I have checked your world (for example here https://www.worldanvil.com/w/aorlis-scott-story/a/hke-government-article ) and tool tips seem to work exactly as expected.   Can you please clarify?

Sure. I've tried doing mouseovers on Safari, my Kindle, my PC, and I'm not getting anything pop up. It is entirely possible that I'm doing something wrong and expecting something else, but...   What I expected to happen would be a text message pop up when I mouseover the category listing. I'm getting nothing on simple mouseovering.   What I did get is when you put the cursor on a listing, with one click where you hold the key down, a window with a ghost version of the target page pops up as long as you hold it.   Maybe I'm using the wrong function.

Can you elaborate on what you mean by "category listing" ?
