Rightclicking any file in choosing a trusted application-> comodo hungs up

hi everyone!

Don´t know if anybody got the same problem. When i´m choosing “define a new trusted application”-> “select”-> “browse” and then rightclick on any file, comodo will calculating ´till end of time. Taskmanager can´t end the firewall, i can only turn off the computer.

Nothing big, it´s just bothering me.
