--- Comment #5 from foobard jens@porup.com 2008-11-10 14:01:13 --- in wine 1.1.8 voipcheap installs but still fails to run. This bug should be re-opened.
After installation it prompts you for your details for a new account, including a captcha. Then it hangs attempting to contact the server.
Testing this app caused my X session in Ubuntu Intrepid to crash twice.
