First line missing from TPWrite in teachpendant

Simotion

I have the strange effect that on my teachpendant of the IRC5 I sometimes don't see the first line of my TPWrite command
My code is just :       
    TPWrite "Choix 1 pour DC 100/110 X 10 ";
    TPReadFK answer,"Faite votre choix","Choix 1",""," "," ","";
What could be the reason for the first line not appearing?

Hello Simotion,

 

do you use e.g. interrupts that execute TPErase; or TPWrite ""; than your TPWrite will disappear and the remaining TPReadFK will still wait for your answer....
