This is very strange, because this is the first I've heard of a multiple response item showing the continue button when being used with the duration parameter. I will look into fixing this but in the mean time, I don't know what else to suggest. One possible fix would be to eliminate the continue button altogether for this experiment. If you can get by without it (e.g., using key navigation only) then you could simply blackout the "continue.bmp" image in the c:\medialab\graphics folder using any image editor. Of course, backing up the original for future experiments. Also, If you use d29 or any value less than 30, you can circumvent the countdown function if you are concerned about that. It kicks in only for duration values of 30 seconds or more.
