it's dogish even when using a digitizer because it still communicates
with the display. We don't have an ALTEK but a CALCOMP, and the new
v.digit works well with this under 4.1.x (not 2.x). These seems to
indicate that the problem may be with Solaris and/or the something
specific to the altek. We just recently moved everything to 2.3, but I
haven't had a chance to try it yet.

The "puck must be on the pad" problem has/had to do with the way
that the software are designed. I thought that this was fixed, but
maybe not.

Another possible reason for v.digit problems that I gathered from sun
gurus was that the serial port interface was supposedly changed on
newer machines.  I can't confirm or deny that this is the problem (I
lean towards the latter), but only offer it as another possibility.

you're correct. The old v.digit is not v.digit2. As I recall, 
instructions for using the older one are at the end of the installation
