Shapes do not automatically connect

[Felipe Gac Tapia]

I dont know if this is a "feature" of Visio 2003, but there used to be a time
when I would drop a shape on top of another shape and they would
automatically be connected. Reading some of the other posts led me to try
these options:

For the rack shape - the group into which you want to drop shapes, do this:

Format > Behavior: check "accept dropped shapes"

For the shape that gets added to the rack, do this:

Format > Behavior: check: "Add shapes to group on drop"

Along with those suggestions I've tried modifying other shape behaviors as
well as the snap and glue options but have been unable to solve the problem.
I hope there is something simple I'm just missing.
