Entire PDF page gets highlighted Blue

Also note you just click again and the blue goes away. Just tried it on reader and even when you dig into the view menu and choose the hand tool it doesn't stick, if you hold down space though you can click all you want and no blue 🙂

I was bothered by the same thing, and as long as you stay on the hand tool instead of the pointer tool and have the prefs set like they suggest here the page doesn't turn blue when I click in the middle of the page. Hope this helps Gazelle2219673792fq. GG

It happens because the page is an image. To disable it try the following:

Go to Edit (or the app menu if you're on a Mac) - Preferences - General and tick off the box next to "Make hand tool select text & images".
