Omniplan won't highlight my critical path, except the last two tasks.

A similar question has been asked previously:

However, I have attached a screenshot that shows that there is no reason that the previous tasks should not be highlighted.

This has only recently started happening with my project.

Is there any way to get information showing why Omniplan won't highlight the critical path?

Figured it out - there was something buggy about the second last task. I just had to delete it and re-create it and the critical path worked again.

The start date of that task was locked. No matter what you do with the tasks leading up to it, it can't start earlier. You can't shorten the project by messing with them, so they aren't critical.

I can't figure out what it really shows and does?

Braininside, see the glossary:

The critical path is the series of dependent tasks which, if any of their durations change, will cause the whole project's duration to change. You can check the critical path from the View menu or the Critical Path toolbar button.
