Difficulties with Go Integrator

Difficulties with Go Integrator

Has anyone else had any trouble with Go Integrator?  I have set it up in line with the instructions but there are a few things that don't seem to work properly with Zoho...

1) Click2Dial just doesn't work.  The green phone symbol is there, but it doesn't actually dial.
2) If you click on the button to add an activity log during a call, it creates a new outbound call activity even if it is inbound and this field is locked and cannot be changed.
3) When you complete the call, another call activity (this time with the correct start time/duration/direction) is created but it doesn't navigate to it to allow you to edit it - you just see a duplicate activity in the closed activity history

It's all very strange.  I will be asking Mondago, but wondered if anyone else had either similar issues or had got it working properly.
