File comparasin question

[Parblu]

When EoF came out I had a problem where the new achievement point window would just show as a black box any time I did not have the default UI's loaded. Somewhere here I found a reply to another person's post offering that they could compare two default files with two custom UI files line by line to see what was different or missing one from the other...

This was exactly what I needed... I found the missing line for the achievement window and it's worked ever since. I've got the same problem with a frostfell window that I accidentally opened last night and now I cannot find my notes or the poster's helpful comment to remember which files to compare.

Can anyone point me in the correct direction? Thanks for your help. I've searched for an hour trying to find the original post but have not had any luck.
