Users can't edit pages when logged in.

Having an awesome issue with pages not being editable when logged in under my clients user account. Tried a million things - but it doesn't have anything to do with the access control or roles - its bizarre - and I still don't get it, but this is what I found:

In short - I had to change my default input format from FULL HTML to Filtered HTML. Weird. It's time that I come up with a good input format for using TinyMCE, soon I will document that here.
