XC-Soar PDA weirdness

I have a question regarding XC-Soar and am running it on an iPAQ3850.
I loaded the latest version 5.2.3F.

When I first loaded the program everything worked as advertised,
except I've never seen the landable fields show up as colored dots,
well yesterday for one session they showed up as yellow dots, but not
anymore. Also the Visual Glide feature worked for awhile, and now does
not appear when activated. Also seems that the set up profile I am
constantly resetting does not hold after closing the program.

All in all I am flying with this latest release and am happy with it,
and the above mentioned items are more a curiosity than anything else,
but I am curious if it is my PDA ignorance, or is the program still
somewhat "buggy" I've also heard PDA's can be somewhat tempramental.

Thanks,
Brad
