stimContinue works slightly different than, I suspect, you expect it to.
The QRTEngine goes over each stimuli that you’ve defined in a trial, and per stimulus, decides whether the current stimulus should be the last stimulus on the current screen (page), or if it should look for another stimulus. Setting stimContinue to true is equivalent to telling the QRTEngine to not cut off the page at the current stimulus, but look for another one.
So, if you have 3 stimuli, and don’t set stimContinue for any of them, it will show each stimulus separately, in sequence. However, setting stimContinue to true for stimulus one, would cut off the ‘page’ at the second stimulus, so what you’d see is stimulus 1 & 2 being displayed at the same time, but stimulus 3 being displayed on its own.
Hope this helps,
