the described behaviour is maybe not ideal, but it's how things are supposed to
work, so it's a lack of features, not a bug.
If you want full control over the mouse, you probably will need to fake the
drawing tool by using the drag command within a repeat loop. However, then you
also need to accommodate for the problem that you are drawing in the opposite
color, and somehow disalow the brush from becoming a zebra stripes creation
tool. See this example for what I mean (drag slowly for problem):
on mouseDown --works only with pointer tool
put the mouseLoc into theCurrent
repeat while the mouse is down
--wait with messages --uncomment if slow, allowing messages can help
--add check to disallow zebra stripes here
if the mousecolor is "255,255,255" then
set the brushcolor to black
else
set the brushcolor to white
end if
choose brush tool
drag from theCurrent to the mouseLoc
put the mouseLoc into theCurrent
choose browse tool
end repeat
pass mouseDown
end mouseDown
