Rich Text Editor on WordPress does not work correctly on Safari 3 beta. It supposed to be known problem.

Rich Text Editor – Editor that is used to write Rich Text Format files. Rich Text Format is a proprietary document file format developed by Microsoft for cross-platform document interchange. Most word processors are able to read and write RTF documents. From Wikipedia.

In other words Rich Text Editor is ‘I see what I write’ or ‘I write what I see’. the opposite is the great tool Latex, where all text is entered together with commands, that are responsible for different settings borders, symbols, etc. etc. That allows to avoid ugly documents, that sometime are created by “standard” office programs.

It looks like Safary is mixing commands from WordPress, as spacing, paragraph, links, images are not taken in consideration.

So currently either ‘Code’ should be used to type post (similar way to Latex), when “all rules are set with commands”, or use other browser like Camino.
