Alright, deleting the nicetitle.css file DOES seem to eleminate the pop up window.
As a side note, if I delete the nicetitle.js file, when I hover over the COMMENT title, my Safari brower pops up it’s OWN little window. It’s yellow and says “Comment On *Blog Title*”. And of course whatever the blog title is, is what’s there instead of what I typed.
Also as a note, when I only have nicetitle.css deleted and not the nicetitle.js file, while no window pops up, I do notice that the scroll bar shortens, as if some kind of content was added to the page, and it had more to scroll. When I move the mouse off the link, the scroll bar lengthens again.
I’m not sure what that means, but it doesn’t really effect anything major that I noticed.
