I have 2 problems with our experiment on DirectRT:

1) When participants accidently hit the ESC button it actually works even though I set the parameters so only 1, 2, and 3 should be accepted as responses. None of the other keys work, but the ESC button. How do I get this to "turn off?"

2) On 2 occassions a participant was completing a task in DirectRT and a check mark appeared in the middle of a blank screen after their response. We cannot figure out what triggered this, but the system locks up when it happens. This task involves imported photos and a scaled response followed by a separate free response question. The check mark appeared between the scaled response and the free response. We are running DirectRT through MediaLab. Any ideas?

Thanks,

Beth Hentges
