goautodial bug fix

I have install and configured a "goautodial" and had a little problem. When I dial a list, i can dial the first lead, talk to the lead, hand up the phone call, select the status of this phone call and click on submit. However, after all of that, the dial next button is not available to click so I cannot dial the next lead. This can be solved by click on 'manual dial' -> 'preview call' but this does not make sense. Need some to fix this small problem. Maybe it is just a setting problem. here is the account you can test with, please select "test campaign" [login to view URL] phone login: 8001 phone pass: prWXChl4 agent login: agent001 agent pass: Okp4KL
