first stimulus

I’ve used superlab for a number of years now but I was planning to get students started using it and I was planning to show just a list of 10 words at 1 sec each. For some reason it showed the first word for 10 seconds and zipped through the rest. I tried it with each words as one event and also with a list of 10 words. I am sure I set the time limit each word to one second. I’ve gone over this a dozen times. No idea.
