I don't know if this is related or not to what you are saying, but I have been seeing a lot of error messages popping up telling me Google Maps wants to FC when I am not even using Google Maps, but am instead reading articles on the MaximumPC or MaximumTech website using either Opera Mini or Opera Mobile on the Ally. I just dismiss them and continue on reading.
When I do use Google Maps or Latitude, it seems to work well and does not FC at all. So I'm not sure what to make of all this. On a somewhat related note, I have been noticing over the past couple months that opening GMail on any of my PCs seems to take many times longer to display than it had been originally when I got the Ally. Sometimes half a minute before it will display anything. That is using either Firefox 4 or Firefox 3.
And, when opening up Jorte, the calendar app I generally use on the Ally, I am now finding it takes over 30 seconds of blank screen before it displays. I know the first thing it does is sync with the Google Calendar before it will display anything.
So maybe Google is having some kind of server issues "down on the farm"? If so I hope they get things back in order soon. All this lag is a PITA.
