Hi, very smiliar to yet slightly from the bug report no: 2006627 --and much more recent: Skim 1.3.21
I found out that highlights in some of the older pdf's have shifted a little off the main text. The content of the highlight remained intact, no problem there...
What might be the source of the problem?
(The pdf was not a jstor file)
Thank you very much!
(Attached is a screenshot. The problem is on the middle of the page (older highlight). The bottom part (new highlight) works correctly.
