no trouble
Go to your EverQuest II directory
You should find some files that are named something like so: SERVER_CHARACTER_eq2_uisettings.ini
make sure your not logged in game then copy then to another folder or rename them to SERVER_CHARACTER_eq2_uisettings.ini.bak
Then log in and you should see all your windows all over the place in a jumble.
You may move them all to where you would like then try that.
Or, you may use the window placements wizard available in the thorui application. Basically you choose which setup you want and it does the rest.
Few more writeups in the eq2interface forums as well if I'm still not clear.
