Text in itemize in column with tikz exeeds margin

I'm new to tikz but I don't think the problem is tikz itself. What I want to obtain is simple, a list of file names with an arrow for each element pointing to the middle of and interval of a tikz image.

Any idea of what I'm doing wrong? Thanks for the help!

• I think the tikzpicture environment miss the option remember picture: this means that the point t1 isn't know when you are trying to draw the arc. – Claudio Fiandrino Jul 24 '13 at 10:50
• Welcome to the site! Thanks for providing a MWE :) @ClaudioFiandrino yep, that's what I got too :) – cmhughes Jul 24 '13 at 10:52
• @cmhughes I noticed and you were faster than me of 4s :) What about to improve the answer by shrinking a bit the font size of the file names (I guess \footnotesize would suffice)? Upvoting meanwhile. – Claudio Fiandrino Jul 24 '13 at 10:58
• Thanks for the help, I've added the [remember picture] by the way there still are some things I don't understand, why the file names goes on new line? and why they cross the right margin? – drkg4b Jul 24 '13 at 12:26

I think you're missing a remember picture from the tikzpicture in your second column

I have also removed some of the unnecessary packages from your preamble- a lot of them are loaded by beamer.
