Usually unexpected or seemingly missing functions are caused by wrong settings. Thus resetting Remote Buddy to its factory defaults can be helpful.
To reset Remote Buddy's settings to its factory defaults, please perform the following steps:
1) Quit Remote Buddy.
2) Open Terminal and type
mkdir ~/Desktop/OldRBSettings mv ~/Library/Preferences/com.iospirit.*emote*uddy*.plist ~/Desktop/OldRBSettings/into it. These commands create a new directory called OldRBSettings on your desktop and move your old settings inside it.
3) Start Remote Buddy.
