Sorry for the delayed response - I'm not playing WoW for a while now (haven't even tried mists yet). I wasn't playing the game during WotlK but I did come back to play Cataclysm (and played quite a bit).

I think I tried one time during Cataclysm to put together my old UI. And after downloading all the addons I used to use to make it, I managed to get most stuff set back up how it was... that is until it came time to setup Pitbull =p It had changed so much, in terms of configuration menus and dogtags and whatnot.. that after an hour or so messing with it I just said "oh well, I don't play enough anymore to bother tearing this new version apart"

Been playing Diablo3 hardcore-mode with 90% of my gaming time for a long while now and haven't touched WoW.. I did just get an offer email from blizz, for a 10-day free trial of MoP though.. So I'm gonna give it a try here soon and I may try the pitbull thing again while I'm at it. I'll let you know if I have any success with it

You just need to replace the Normal.tga file inside the Masque_DsmFade textures folder - with a different Normal.tga file that is modified how you like it.

I made a quick one for you, with a rounder outer glow. I don't think I can attach a file here, so I just uploaded it to a free file upload site.

btw: to download the file from the above link, just scroll to bottom and click "Regular Download" then wait 1 minute for the wait timer to end and click the download button that appears. I dont think it will work if you use any download accelerator plugins so just use your browser's default download method.
