I have had this problem for a while. Little quirks on the system. If I put together a post, I have to make sure I copy all the text or else it might not save it.
The biggest issue is this split-screen I get. When I switch to HTML view, the WYSIWYG screen pops down underneath. I have posted a link to an image here:
Now, I have turned off all plugins, so that isn't it. I have deleted all WP files and copied new. This problem has been following me since v.3.0
Someone suggested it was a theme problem, but I have also changed themes on the site.
The only thing I can think of is a rogue MySQL command. I have cleaned out my database as best I can.
Is there anything someone can suggest? I don't know where to go from here (besides a completely fresh reinstall).
Thanks in advance
