Sharepoint wiki

I really dislike the Sharepoint built in wiki.  I find the WYSIWYG annoying.  When I try to highlight a block of text, it takes a few seconds for something to happen.  The background color of the text doesn't change though.  You just notice that the cursor position has changed.  If you hit Control-C to copy, then the background color changes.  When pasting the text, the page seems to randomly decided if it should put a carriage return.  If I put the cursor at the end of a line, the cursor disappears after a second and magically reappears at the beginning of the next line.  The arrow keys only work about 70% of the time.  It is very frustrating.
