How to set the layer of draggable objects?

I have 12 groups of objects (each consisting of a rectangle with a
label) on a card and need to set the layer of each one that I click
on to be higher than all of the others. These groups are set up to be
able to drag them around the card using the script from the Tip of
the Week section of runrev.com with the addition of one statement to
set the layer of the group.
set the layer of me to top
put true into lMouseDown
on mouseMove x,y
if lMouseDown then set the loc of me to x,y
put false into lMouseDown
The group does move to the top layer. However, sometimes the group
doesn't seem to detect that I have let go of the mouse button and the
movement of the object continues to track my mouse.
I thought that maybe I could simply put an if statement in the
mouseDown handler and check to see if the group was currently the top
one. The only way that I can think to do that is see if the layer of
the group is less than the number of card parts. This doesn't seem to
solve the issue of detecting the mouseUp.
Does anyone know a way around this?
Also, I would like to set the layer of the group to be higher than
any other group, but no higher than the buttons, or possibly other
objects later, that are on the card. How do I go about doing this? I
can't simply set the layer to top to accomplish that as the layer of
the rectangle will then be higher than any buttons as well. Any
suggestions here would also be appreciated.
