Hi Denis
Thanks for your help!
Unfortunately my problem goes on, even if i replace the direct contact with a positive transition one. For example, to enter a keypad variable entry, i usually have to press ENTER twice, one to be able to enter the value, and another one to confirm. With my external button, i can "press" the first ENTER without problem, but i can't confirm the value, in ohter words, i can't "press" the second ENTER. Same thing happens with the arrow keys,
