Been a while since i did enything with LS so i have a question.
Is it possible to have a bg image with a pattern in a popup?
Or perhaps something like repeat-left repeat-down with a smaller, lika webpage?
Or perhaps if i have a 200x200 px, the popup could display as much as it needed and not squeeze it together?

Hope you know what i mean.

Use xPopup, the older versions pre 2.x support this, as well as the newer 2.x (xPaintClass versions).
