I received my first call whilst I had a number of windows open on my Mac. An Express Talk dialogue box appeared on top of everything but click on it as I might I could not get the phone to pick up. When I did finally get to the app window I must have hit the wrong button and the call was lost - and now no call log so I cannot return the call.
The help link brought up the Mac's manual - so no help there.
Now I appreciate that this is all my own fault as a user but before I buy the software I would expect to be able to have had some success with it. So what is the wisdom of this place's experience?
