jQuery UI dialog box not positioned center screen

Question

I have a jQuery dialog box that is meant to position in the middle of the screen. However, it seems slightly off-center vertically.

Here is the code:

Answer 1

$("#dialog").dialog({
       autoOpen: false,
        height: "auto",
        width: "auto",
        modal: true,
         my: "center",
         at: "center",
         of: window
})

This solution does work but only because of the newer jQuery versions ignoring this completely and falling back to the default, which is exactly this. So you can just remove position: 'center' from your options if you just want the pop up to be centered.
