Plan G freezes in Google Map mode

[stanshear]

Forgive all my dumb questions, but I'm just getting into Plan-G and finding these things out.  When I zoom into Google Maps with the setting about half way along the slider Plan G just freezes and I have to shut it down with Task Manager and reload it.  Not serious, because I won't be using Google Maps so much with all the other great options available, but just want to know whether anybody has experienced this.
