When I read that comment I decided it was time to uninstall Adobe Reader and found it was taking up 145MB of disk space. Many thoughts went through my mind. Maybe there was whole virtual civilization in there and I just wiped it out. Maybe Adobe Reader is skynet and I'm John Connor. Maybe it was time to find a new PDF viewer.
My first try was Foxit. I found its short name promising. The installer confused me with talks of Javascript and safe mode, did not look good. First paper I opened crashed the program. *sigh. Sumatra was had the colourful charm of the web in the 90s. I was almost ready to give up the resistance. I took a deep breath and clicked the link of the installer. Before the next breath it was installed and I was opening PDFs that looked just fine.
TL;DR remove adobe reader, install Sumatra
