Alan and Bob,

   It appears that what happens is that if nothing is put in the sign for
declination, it uses whatever was there previously.

   For example if there was a plus sign in the in that box and it was
deleted, the slew will be to positive dec, and if there was a negative sign
in that box and it was deleted the telescope will slew to negative dec.
This is true of both 2.35 and 2.36 ( and probably earlier versions as well
).

   I don't really think this is a bug, but to avoid possible confusion we
might want to either force the user to put in a sign, or have it default to
positive if it's empty.
