Back when I used a Palm V I used to have a hack that removed the lines in
text fields. How do I do the same on my Treo 650? I've found PrefsPlus but
it doesn't seem to run on OS5.

Ideally I'd actually like some control over the dots (single-pixel instead
of 2x2 block; lighter colour) but I'd happily just remove them completely.

Unfortunately, just changing the colour scheme (using Butterfly, for
example) is out of the question as I use Profiles on my Treo and use the
built-in colour schemes to signify which profile I'm using. As soon as I
change to another profile, any Butterfly-created changes are lost.

Unless, of course, anyone knows of a way to edit the *built-in* colour
