I am having ongoing problems with my textbox tools. Typing is distorted, especially using the space key (which doesn't do anything) or any punctuation marks. After using punctuation marks, cursor position changes and/or text starts in putting back to front. Upon trying to re-edit a already used textbox, I am unable to select any text or edit these. I have tried resetting all settings and completely uninstalling and re-installing the program with no change. My keyboard works fine and all other programs are running normally. Occasionally images and imagery isn't visible in Bluebeam Revu when it is still present and visible in the same files on other pdf viewing programs. Please help.
