The code Drums is talking about has actually already been incorporated for the last few versions (basically since he posted it)
. I haven't personally had an issue with the examine window appearing off screen since then, but I'll test it next chance I can and see if left too many parent's in when adpating it or otherwise typo'd it and have just been lucky.
In the meantime, if you want to upload and attach your character's eq2_uisettings.xml file I'll take a quick look at it and see if off-screen clones are the problem.
