Examine window sizes are semi-hardcoded, kinda like the bag windows. Most of them figure out the size of the contents, then pad the window size assuming you're using the default frame. Results in an annoy amount of extra space at the bottom if you're doing a streamlined skin.
Might I suggest ger's mod.. I used his to make mine. All I did was add the titles on the window when is not over window.
I would link to his file, but for some reason it is no longer up. Let me make a non title version of mine. I will preserve the on hover mouse turns on control buttons.
It's awaiting reapproval. I fixed a mistake I made in slot naming on the full-size, removed the problematic click-through code, and changed the grab handle to have the bag name as its tooltip.
