Preview highlighting disappears after save/reopen
I just spent 4 hours highlighting relevant phrases in a PDF of a scientific paper using Preview (for a presentation tomorrow). After saving and reopening the file, most (but not all) of the highlights are gone. They also don't show in Adobe Acrobat Reader. Going back to previous versions (I saved frequently while working) does not help because most of the annotations that I had created before each save apparently disappeared during those save's as well.
I'll have to redo the work (in Acrobat this time). I'm not amused, especially because this problem seems to have been reported multiple times before. I would hope Apple addresses these kind of serious issues more quickly.
