```Hi,

I am trying to use the routines in  ExtendGraphics`Tick`. However, I keep
getting the same error when trying to use these functions.  As far as I
can tell it stems from the fact that the subfunction TickPosition,
although defined, doesn't return any numbers

Here's an example of a session

In[12]:=
<<"ExtendGraphics`Ticks`"

Try and run TickFunction

In[15]:=
TickFunction[1,2,MajorStyle->{Thickness[0.02]},
MajorLength->{0.06,0}]

Transpose::nmtx: The first two levels of the one-dimensional list
{TickPosition[1,2,8],<<40>>[TickPosition[1,2,8]]} cannot be transposed.

Transpose::nmtx: The first two levels of the one-dimensional list
{TickPosition[1,2,8],<<40>>[<<1>>],{0.06,0},{Thickness[0.02]}} cannot be
transposed.

expected to be the same.

Join[Transpose[{TickPosition[1,2,8],
ExtendGraphics`Ticks`Private`TrimDecimal[TickPosition[1,2,8]],{0.06, 0},
{Thickness[0.02]}}], TickPosition[{32,,{0.003125,0},{Thickness[0.001]}}]]

If I inquire about TickPosition it appears to be defined

In[13]:=
?TickPosition

Out[14]=
TickPosition[ min, max, num] returns a list of at most num nicely rounded
positions between min and max.  These can be used for tick mark positions.

However, when used the function just returns the command used to call it
In[14]:=
TickPosition[1, 2, 5]

Out[14]=
TickPosition[1,2,5]

Has anyone else seen this problem or does anyone have any ideas what's
going wrong here.

BTW: I just reinstalled the ExtendGraphics files and that didn't help
