We use adobe reader to access the internal secure documents with username log in and password. Normally these files are electronics schematics made from an OrCAD software. Recently when I found a problem in adobe reader during display of these secure documents. The text and lines all will be displayed in gibberish way and sometime the desktop background also display in adobe reader secure documents. I tried to repair the adobe reader, unfortunately that didn’t work. But this problem only solves after I try to uninstall and re-install again only. But it’s not possible to uninstall and re-install again and again whenever I face a problem with it. And, I found the root cause of this problem is only when I let the secure document open and make the system (PC/LAPTOP) sleep without closing the reader. I found this problem with other systems also.

Laptop/PC details:

Make: Lenovo ThinkPad.

Operating system: Windows 11.

Adobe reader: Latest Version. (Tried with older version also.)
