google map freezes touch pro if not exit after use?

[lettcco]

I have a stock sprint touch pro that was used to replace my mogul. I love everything about it, but one quirk I found annoying is that with the latest google map 3.0.0.12, if I just let my phone go to stand by mode (screen off), then when I try to wake it up by pressing power button, nothing will happen. At that point I can only hit the soft reset hole in the bottom. When I have my mogul before I was always able to wake up from stand by with google map on...the worse would be I can't lock on the GPSs anymore. Does anyone have similiar experience with googple map?
