OK, I had a weird one happen.
I went to start Dolphin HD browser which is on the top right corner of my main home screen.
Right next to the GPS (on/off) widget.
I don't know what I hit (because i can't reproduce it) but it brought up a screen that showed all my home screens in one screen (shrunk down). Most likely a motoblur thing, but like i said, I can't reproduce that. I just pressed BACK to get to normal.
Then on my games screen (not the one I was on initially) 5 game icons just disappeared (I put them back from the app menu).
So what's up with that?
