Stefan,
Can you look for a solution for disabling RTS functions keys (F1 to F12) when the Rebex control has the focus?
When you are in an app that use function keys like midnight commander and use the F10 key to exit, both the Rebex control and RTS recieve the keypress event.
In the case of F10 key, the ribbon got the focus and the Rebex control lost it so any new keystroke go to RTS instead of the terminal!
Maybe when the Rebex control got/lost focus, you can temporarely disable/enable some shortcuts in RTS?
