Hello,
I've been trying to create a skin with SkinStudio for a long time, but every time I tried too I got this Glitch:
There is an extra 1 pixel line between each Left, Right or Bottom border to the actual content of the window, which is either transparent, stretched from the window or the border or just random.
I've made Screenshot of the problem:

Can anyone please tell me how do I fix this problem?

Thanking in Advance,
LIJI
