That raid window has been fixed like 3 times now
... I dunno what there doing but it kept breaking untill I re modded the new default one so this one works with the right click menu now so you will be able to set it transparent.... It may also help if you turn the background on for it so you can resize and position it again if you been trying to move the old versions about..........
The raid window should take up the whole of the playable area!
Have frame and backgrounds turned off
And in the right click window options enable "clickthrough" for the window
That way you can move the raid group boxes anywhere you like again and it behaves exactly like the old one did oks...
Look for unpdate tonight as I have been messing with a few other windows also....
