If you look at the file above, you’ll see a bunch of boxes. If you hover over the right edge of a box, it will glow green, if you then click and drag from that edge, what should happen is a blue line should extend from the box to the mouse. However, it doesn’t.
Furthermore, the endpoint of the blue line (which should be the mouse) is somehow related to the numbered box on the right in the middle. If you drag that box around, you’ll see the behavior I mentioned above change.
Here’s the bit of code that draws that line:
neatGlobals.vars.moduleA.preConn.graphics.clear();
neatGlobals.vars.moduleA.preConn.graphics.lineStyle(1,0x0077aa);
neatGlobals.vars.moduleA.preConn.graphics.moveTo(mod.x+mod.width, mod.y + (mod.height/2));
neatGlobals.vars.moduleA.preConn.graphics.lineTo(mouseX, mouseY);
