Module freezing when try to configure it.

[planetpcsales]

Hello,

In our presta shop Back office, Modules page, we’ve got a Wizard works with 2 modules – Left editorial and right editorial. When I try to Configure the Right editorial the screen freeze and the following message appears:

A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.

Script: http://www.__________.com/js/tinymce/jscripts/tiny_mce/tiny_mce.js:1

Well, if I choose to continue the screen freezes, if i choose to stop it, everything in the configure screen is missing and the field is white?! Thats not possible because we’ve got 2 adverts, which I can’t see.

Help!
