The map goes "offline" and goes black for a second or two EVERY time you pan or zoom the map.
I use the map module every day and this error is new and really annoying.
This error/problem has been reported by many people already and IIRC a bug report filed over at the Photoshop family web forum site.
It takes quite some time. Wonder if someone is working on the problem and if we will hear a "Yes, we found the problem and we are working on it"?
I can tell you that the issue is known and was caused by a change at Google.
A fix is being implemented and will be available in a future release, probably the next.....
