Tiny MCE on Drupal7.9

Hi,

It's just a question (for the moment),

I've install drupal 7.9 and tinyMCE and work on Chrome or IE, I got quite lots' of bug when typing text on textearea :

- Line texte dispear sometime after saving,
- Impossible to make a "table" without spedding hours before the result works,
- If i put a "hr" then result sometime work, sometime not,
- The windows popup for changing the property of an element, sometime open to little, sometime take all the screen,
- When I copy a piece of text on a cell of a table, sometime tinyMCE copy also the information of the table itself, so the past could be funny ..
- the size of the textarea grow to one line per letter I type, so in final I have the very very long textearea
- no way to make the "Define CSS" work ! so I have to duplicat my script.css to content.css
- sometime tinymce, put alone a space on the beginning of a new line or a new cell
- ... many other problem like who make a client will not accept to pay for that ...

so I would like to know, if I'm the only guy who having problem like that (Cause I start on drupal) or if for people how use drupal every day it's a normal way to work, or every one know that tinyMCE is buggy but "that life ..." we don't have other choice on drupal !

Tks for an honest answer to my interrogation ....
