[comp.sys.mac.hypercard] Hypertalk control of lasso tool

I am having trouble using the lasso too to select an area from a
script. I am using HC 2.0, but I don't think that is important. Say I
want to invert a trianglular region. This doesn't work (obviously):

select lasso tool
drag from 0,0 to 0,100 with optionkey -- option key selects region
                                      -- even if it's blank
drag from 0,100 to 100,100 with optionkey
domenu "Invert"   -- or whatever
select browse tool

The second drag nullifies the first and a region with zero area is
selected. I guess I want something like this (it doesn't work):

drag from 0,0 to 0,100 to 100,100

Any ideas? I believe I've exhausted the RTFM method.
