People are happy with the Geommunity suite. I'd say the problem is more due to a Javascript issue on your end. Provide a url so I can have a look or use the Javascript console to debug your javascript issue.
Let me know, it's usually easy to identify.
- Need help? Post the URL of the related page (eventualy as confidential info), it will help solve your issue faster.
- An error, notice or warning? report the exact message including the line number
- If you get a white page , enable error reporting and / or check your server error logs.
