I have used JCE for years in my projects. It's so much better than the built-in Joomla content editor. But it's always been buggy. And recently it's become unusable. The old bug that killed me was switching between WYSIWYG and HTML views would wipe out any changes you made to the article. I learned to get around that one. But recently the Link Editor has completely stopped working. When ever you click on one of the trees in the link editor to create a link, Menus or Content, etc. it never opens. You just see the daisy wheel spin and spin forever. No error, no message, just dead. I don't know if it's Joomla 2.5 or JCE 2.2.1.1 but the greatest single add-on for Joomla has died on me. I hope it gets fixed, because there is really nothing like it out there. Hands down, it was the best.
