I took my time to understand the codes, but I don't find how to make it works. If you click randomly 4 times, you'll be able to make 4 crosshairs, but if you click correctly and form the first part of the main cross, when you want to click 2 more times to make the other part of the cross, you'll only be able to make 1, the 3rd crosshair and not the 4th. I'm using the original posted FLA. I tried overwriting the original FLA with your last script, Nig, but it doesn't create the cross, it only attaches the crosshairs with the lines along.

Try it yourself, click one point, then the 2nd point and create a red or yellow line (part of the cross) then try to click 3rd point and 4th point to cread the other part of the cross (if you made the red one, now try the yellow one) and you'll see you can only make the 3rd crosshair, inmediately shows up the Submit button and you can't click anymore to create the 4th crosshair to creat the last part of the cross. And he is not abcent, he commented yesterday, that's why I commented to and tried to help.
