Hi, A user is currently using Adobe Acrobat Pro DC (Below screenshot is Adobe Reader but used for showing where the issue appears). When opening PDF's intermittently they will appear with a white box covering the section marked in red in the image below. The area becomes unclickable. Nothing happens when you click in any area I noticed that if this were the only window open and the white box was ontop of some other desktop items eg. Recycle bin, word, googlechrome. Clicking on the whitebox where the icons are located actually opens / highlights the shortcuts. It should be just interpretting clicks in the Adobe application itself, not behind the Adobe window. Re-installed adobe, repaired adobe, updated graphics drivers. Please note: Image 1 is where the problem occurs and what actually disappears (Home, tools, file edit view , window, help). Image 2 is what it looks like. Image 1. Image 2. I've never seen this issue anywhere else. Any help is greatly appreciated. Regards Jason ... View more
