[GPSToday]

ScrapMaker, isn't the Sprint Touch the same underlying device as the HTC-6800 (aka Vogue, aka Titan aka Mogul)?
This standby thing has been nagging users with devices built on this popular platform ever since folks figured out how to enable the hidden gps hardware, and it probably continues even with official ROM update releases. And if you dig through this and other similar forums, you will find that heavy users of GPS programs are facing it even when GPSToday is not/was never installed.
By its very nature, installing GPSToday and using it in auto-mode makes you a heavy user of GPS, hence the problems.

We have not had even a single complaint of this problem on other platforms, including those by HTC.
