Can't edit website URLs

When I try to edit the website URLs and hit save it keeps saying “Loading data” but nothing happens and URLs are not saved. I’ve having this problem with prior versions and thought it might be a bug that will eventually be eliminated, but nor I think I might have to change a setting. Is anybody able to help?

Hi,

Install piwik’s version 0.6-rc1, your problem should disappear style_emoticons/<#EMO_DIR#>/wink.gif
