Submit button has to be clicked twice

I have a workaround for this... I handle the try again on a customized Incorrect layer (simply added a video on top of the incorrect slide) with option to retry or continue with on slide buttons). To avoid having users to double click when submitting, I right clicked on Try Again layer, Apply Format > Blank, and in the slide layers uncheck the Dim option. Then add a trigger to Show layer Incorrect When the timeline reaches tie 0m 0s. Works like a charm!
