Unwanted Blue Box (Not in Layers) in Multiple Illustrator Files

[prepress10l71243818]

I've seen this box in a few files now (not ones generated by myself but by others) and have not been able to locate where it is in the file, move it, or delete it. It does not confine the content, it doesn't move when the content moves, it's nowhere on the layers....I'm at a loss.

What is it?? It doesn't seem to have anything to do with print tiling, but it looks similar.

I would suggest you Restart as Monika recommended above.

We figured it out on our end at least for these files! Apparently it was because we were not using the newest version of Illustrator. I still don't know why that would be the case, but it is.

I realize this is an old topic, but I'm curious. Do you have any Esko plugins you are using in Illustrator? One of my coworkers discovered the the strange blue box could be removed by turning it off in the Esko menu item.

This is the real answer. Great Job Mark! Go to Esko Menu and Trim and Media box and uncheck the Trim and Medi box checkmark at the bottom of the menu window.

Window > Esko > Trim and Media Box > Uncheck the "Show Trim and Media Box"
