URLS in content field - BUG in revolution ?

Hello,

I have installed Revolution 2.0.0 RC and it all seemed to be working fine until I tried to save some links in the content field after editing a document.
When I do so the manager hangs.

It is the URL that does it. If I only insert html tags and text I can save the document every time, but If I insert a url (like http://example.com) the manager hangs on the saving notification (I let it run for 20 minutes just in case it was only slow but nothing happened).

I have checked and all the server requirements seems to be met.

I have installed with the core out of the webroot. Could that have something to do with this?

Can anyone help with this ?

Many Thanks in advance

Sounds like a mod_security issue to me, but without more details, it is hard to tell.
