Does that mean that if, say, I have a stack running your script in the
and I'm scrolling a window in Firefox that that scrolling will register
in the LC stack?
The reason I am asking that question is because I don't quite understand
how one effect a mouseUp
while one is scrolling with one's mouse at the same time and the mouseUp
not affecting the frontmost app.
