ive already done all that
i have actually deleted my WTF folder (just then) and logged in and the window was in its place were it should be... weird.
the only reasons i use prat is
1) time stamps
2) class colours
3) i can press up or down to scroll through what i recently said so i dont have to retype (LFG xxx or LF Enchanter...).
if you could add these to nUI i wouldnt have to use prat.
