Well. I've found that the first 3 bytes of this file wymeditor/lang/es.js are containing some bogus data.
This 3 bytes are not being shown on notepad neither notepad++, but using PHP file functions, these bytes are ruining the WYMeditor for IE7.
I hope I've been clear enough to report correctly this (sorry, my english is not to good).
In short: Check in an hex editor the first 3 bytes of wymeditor/lang/es.js.
Regards and keep it up!
Edit: Remember, in English its Spanish, not Espanish.
