Checkbox Borders Inconsistent

[Netcentric Nik]

I have a page from a client who wants their fields to match appearances to a thinner line style than "thin". At first I did not believe it, but upon comparing, this page has two different "thin" borders on the checkboxes. Does anyone know how this is accomplished?

Image (info redacted for client's privacy): Top three are "thin" border style. Bottom four are also "thin", but I can't reproduce this appearance.

It has nothing to do with zoom or "enhance thin lines".

They probably used 'lineWidth' property to set border width:

0 — none
1 — thin
2 — medium
3 — thick

You can try to set it to less than 1 for example, but as you can see from your file, lines doesn't show on every side.

Thanks for the response. How can I change the "lineWidth" property? I only see the preset options in the "Properties > Appearance" tab.

Let's say checkbox name is "Check Box1" and you want to set width to 0.5, there are a couple of ways to do that:
1. Javascript console (CTRL+J) enter this in console window, select it and press ENTER:

this.getField("Check Box1").lineWidth = 0.5;

2. Create button field and under action tab as 'Mouse UP' event add the script from step 1.

3. As Mouse UP event of checkbox:

event.target.lineWidth = 0.5;
