[Sigh! This one turns up often enough to be included on a list of
commonly asked questions, did anybody ever do something about this?]

Your best bet is to install your own vdi mouse button handler, save
the "incoming" button mask in a variable and replace the original value
(if I remember correctly it's in d0) with the value for the left button.
After you've done that jump to the original button handler, the whole
thing needs just a couple of assembler instructions, so it's really
trivial. In your event loop just wait for a left button event and then
sample the stored value for the button that was really pressed.
