Issue with Forum post editor

Hello The WYSIWYG interface/toolbar is only present once in a while, as if I'm keying in a notepad.txt file. Much of the time double line space is filtered out on save or preview. I'm usually stuck in the DREADED SoUrCe MoDe. Some things created in WYSIWYG have been copied after switching to SOURCE so the tags are revealed, then pasted into a notepad.txt file so I can figure them out and use the subset of tags that this forum allows, invalid one are just more text and characters inserted, revealed in the post. An image of a source display of an "image insertion" would be a great boon. Either posted here or sent as a private message. Thanks folks
