Cannot use the decimal point on Collect 1.1.7 on Android 2.1 on rooted e-ink Nook

Since the form works fine on my Samsung GT-I1900 (android 2.2), I am
guessing the problem lies in the keyboard routines that were created for
the e-ink Nook? The nook is great for basic data collection but having no
decimal point on a decimal number variable input (you tap on the . key on
the virtual screen, and nothing happens. It just ignores it, like the
letters) is a major problem. Any ideas about where I should look to find
the source of this problem? I dropped a note at the XDA devs nook forum,
but have not had a response yet.
