Using version 0.9.4.1 (as well as the previous version) cause the Publish, Save Draft, or Update buttons not to function. You the cursor changes to a finger, but clicking the button does NOT save or publish a post.
I have tried this with the default Twenty-Eleven theme and no other plugin activated and the problem exists. If I deactivate Types WordPress Publish/Update/SaveDraft work as expected with Twenty-Eleven or my theme of choice WeaverII-Pro. The site continues to work with 6 activated plugins as long as Types is deactivated. If it activate it the problem returns.
