I’ve had this three days, and here is a summary: Day One - Worked great! I love this app! Day Two - Hmmm, I’m unable to view documents unless I go to full screen mode. Not a big deal, the tool bar is still there and I can access everything I need easily. Minor inconvenience. Day Three - Toolbar is missing and there is a highly distracting big black stripe where the toolbar used to be. I am able to access the menu bar, but I can’t find any toolbar options to correct this. It saved itself from a one-star rating because in the end, it performs the very basic function of displaying PDF’s…at least until day 4.
