Have you searched for "Interface/Tooltips"-stuff and replaced it with "Interface\\Tooltips"-stuff?
If no, please remember that the path to the graphic must include 2 backslashes instead of 1 slash, otherwise it will load the default border.
If using windows XP you may not get a correct search result for this string if you have not activated "filter files with unknown extension". (link to microsoft)
I just saw that nawfal explained it too , thx.
Currently I do not use eepanels, all the borders are done with the tooltip-file or I edited some of the TGA files the addon uses to make it look like I want it to.
Yes it is buffalo. I looked into the buffalo.lua and searched for the frames and found out that the edgefile was set to "" (empty), so it was a matter of seconds to give it the right path and tile and edgesize of 16 (I guess).
