Hello,
I have been trying to get mouse values from the ION system variable
$Mouse. However everything is not working as advertised, or more likely
I have misunderstood how to use this to get my mouse location I keep
getting (0, 0) for the (X, Y) of my mouse, and I don't think this is
correct. Attached is a brief ION Script which demonstrates what I'm
trying to do. Thanks in advance for any assistance or suggestions.
