Issue: After installation of the viewer, Windows file explorer keeps locking up when moving or copying files

A quick solution if you are running Zone Alarm. Their shell extension is conflicting with ours.

If you install this app, http://www.snapfiles.com/downloads/shellexview/dlshellexview.html you can disable the Zone Alarm shell extension (the icon that allows you to scan an individual file).

This makes windows explorer refreshingly quick!
