terminal app in KDE

[djack]

Ik heb hier een cobol app die ik start via een start script.
Onderstaande script start een kassa app in een term windowke ... nu lijkt het dat er bepaalde toetsen de mogelijkheid geven om in de achterliggende shell te komen ... of de process manager,... ik weet gij god niets welke ma is er een slimme manier om dit te voorkomen?
tis niet de bedoeling dat ze ineens in een shell windowke tuimelen ...
