Just installed 6.22. Same exact issue. PBX loads the table the first time, and exits the first time. Reload the table, and its not possible to exit back to the PBX browser. If you manually kill the VPX editor, you get a hang on the loading screen for PBX.
I just now tried the exact same table, but this time it loaded the table, but would not exit even on the first attempt.
Mike, Please link me to 6.07 and I will try that to see if it works the way it should. Thanks.
