Flirc2 Outputs Extra Characters When Remote Pressed

[flirso]

The dongle is outputting extra characters that are visible on whatever window that's open and accepts input (Lxterminal, Mousepad).

Sometimes they appear on button press, other times on button release depending on how quickly you do it.

Is there a way to prevent Lxterminal from receiving input since it is not an interactive shell?

But more importantly, why can't FLIRC only output the intended characters (Ctrl+F1) and nothing more?

Using the latest firmware.
