Does anyone have similar problem? I have CKEditor enabled for my custom rich text area fields on a custom object. The CKEditor included in Salesforce does not work anymore. It refreshes page repeatedly and you can't edit anything.

My solution was to download CKEditor and put it as Static Resource but I had to find the appropriate version (tried 15 so far)...and only one seem to be working with current data - so that it doesn't change it. But I'm still working on it, and haven't found the best solution so far. Any suggestions? Raising a case on Salesforce didn't help me, they told me it should work.
