Great machine but:

When my 770 is in its case (screen out) and I try to power it on, it doesn't want to turn on (sporadically). Does this have something to do with the little silver buttons on the inside of the case?

It seems to have an auto shutoff when its in the case (screen in). Is power totally off in this configuration? Or do I need to press power button for "permanent off"?

I can't seem to download Mapper software from this website. Can someone help me with downloading procedure?

Thanks, JeffB
