Sorry Hazel...I have never seen such a thing. Doesn't mean someone won't have a quick fix though...could just be some setting but I can't imagine what good it would do. It sure looks a bit TOO weird to be random in a way though.
Selecting individual words or sentences are fine. I'm basically looking at PDF files for school work. I noticed that they happen mostly in Powerpoint documents converted to PDF, but if i highlight PDF files that were Word documents or Articles, it's fine.
It sounds, then, like you're getting PDF files that have been badly/wrongly converted from PowerPoint. Why don't you attach one of these files (or a page thereof) here so someone else can check whether that's the problem?
So it's not a unique problem, it seems. I don't suppose you could post a page (or whole PDF) that demonstrates the problem, DRbadger? Not that it'll necessarily help anybody fix anything, but I and I'm curious what the heck could be going on with those files to cause such a weird symptom.
sorry to reply an early post. I have encountered the exactly same problem... very weird.
I know how my problem occurred. but don't know how to fix it.
1. I OCRed the doc in acrobat adobe... at this point highlighting with preview is totally fine. but then the file won't scroll smoothly in preview because the different engine used.
2. So I printed the file into a pdf in Preview. The file scrolls smoothly but all the highlighting is in that weird shape. very annoying.
Saving the file as a new pdf in preview is actually what caused my problem.
1. When I am highlighting the text (left click being pressed), the text is still properly highlighted until the moment I release left click on my mouse.
2. I don't think i've ever encountered this problem until the use of Snow Leopard with a new Preview.
Hi, I've had the same problem recently and this solution fixed it. Although I'd just like to add for the next few people who will see this : the "Save as" function is now the "Export" function in the file menu.
