I am trying to write a DA in LSC that uses several ListManager lists.
Specifically, I have two lists that are in the same rectangle - at any
moment only one list is active and I LUpdate only the active list.
Both lists contain text in each cell (list def proc = 0). The lists are
being drawn correctly, the problem comes in selecting cells in either list.

When I get a mouse-down event I call LClick and then LLastClick.
The cell selected always seems to be one cell below and to the right
of the cell that I actually click the mouse in. Partly because of this
(I think) I cannot select cells in the right-most column in a 2-dimensional
list or the bottom rows in a 1-dimensional list; although I CAN drag the
mouse and in that way select these cells. Moreover, I never
get a double-click, even when I click the mouse quickly in the same
cell several times. 

My question is: is there something that I don't know or should
be asuming when reading the InsideMac IV chapter on List Manager.
I mean LClick should track the mouse and select the appropriate
cell right? Is there any weirdness that I should be aware of when
dealing with List Manager events? As far as I can tell, none of the
TechNotes deal with the list manager and I have not been able to find
any sample source code. Is anyone familiar with this problem?

Now, I am probably doing something obviously wrong, but I cannot figure
out what it may be.

Thanks for any suggestions,
Dawson
