This sounds similar to a problem Simon Lord posted some time ago. In
that case, following a mouseDown in one button, the subsequent
mouseUp went to a different button if the pointer happened to be over
it when released. I don't remember the details too well, but I think
the problem was caused by a "repeat until the mouse is up" statement
in the mouseDown handler. It was possible to solve the problem with
either a mouseMove handler or a "send ... in" message.
In general, mouseMove and "send ... in", apart from avoiding the
above problem, are more flexible and give you greater control than a
"wait/repeat until the mouse is up" which holds everything up.
To achieve a similar result as the "repeat until the mouse is up"
statement, something like this will do.
on mouseDown
<some stuff here>
send "doCleverStuff" to me in 10 milliseconds
<some more stuff here>
end mouseDown
on doCleverStuff
if the mouse is down then
<do something>
send "doCleverStuff" to me in 10 milliseconds
end if
end doCleverStuff
