Editing Post Titles

[perfphysio]

Hi guys

I have seen this posted before however it is never posisble to find it again by searching so I am posting the question again. Also even in the past I have not been provided any solution.

Problem: Someone has a typo in the title of a post.
Admin: I go in an edit the post title.
Result: The actual post title when viewing the thread is updated.

Continuous Problem: The post title on the homepage of the board for the most recent post column and also in the post title for my RSS feed remain unchanged.

I have run all admin features to update post counts, title etc. but this makes no difference.

This must be a very common issue and so the answer should be very simple. However I still don't have it.

Hoping someone can clearly explain the way to resolve this,

thanks
