the "enter" key has to be pressed twice to trigger the event

Hello everyone
I have an acquisition setup and i want to log measurements only when i hit a certain key (this case "enter"). The problem is that I have to hit twice the key in order to proceed with the log and also that the event is triggered with any ascii key (e.g space) but you have to hit it twice..

It is my first attempt to use the event structures so it is something trivial i guess.
any help will be appreciated..

I attach an example of what i am trying to do.
Lots of thanx in advance
