I'm a HyperCard programmer (of sorts) who is going to be making Rev stacks
and transferrring stack handlers etc., from HC, very soon, so I'm very far
from being a Rev expert, but I do know some things about HC which has many
In HC, the 'send mouseUp' command normally belongs in an offscreen handler
in a card, bg, or other domain or object. You can, of course, use a mouseUp
message in a button to 'send mouseUp' to ANOTHER object, but NOT to itself.
HTH, and best regards,
