Context Help works great on our project, and doesn't give any problems. That is, until we installed Homebox. Homebox required JQuery UI, and that one messes Context Help up.

If you use the JQuery UI library 1.6, the accordeon in Context Help's "View all" tab is gone. It shows as an unordered list then.

If you use the JQuery UI library 1.7 or higher, the accordeon's there, and Context Help works just fine, except on pages where JQuery UI's used. On those pages, the "Help" button doesn't do anything at all.

I'm not sure whether it's a JQuery UI issue or a Context Help issue. Seeing as JQuery UI's an external library, implemented into Drupal using a module, I guess the conflict's more likely to be solved on Context Help's side. Hence the issue here.
