MediaLab freezes between transition of questionnaires and DirectRT

[MandaHyde]

Access was not open, but I just happened to have the data folder open and saw a temporary Access file being created while MediaLab and DirectRT were transitioning. I opened Access from the Start Menu and when I closed out of Access and reran the experiment, it worked fine. Now if we open and close out of Access before running the experiment, it works, but without doing so, the transition faiils.

I have two DirectRT input files within a MediaLab experiment that uses a responses.xls file. DirectRT often freezes when running experiment conditions that run questionnaires that modify the responses.xls file before running DirectRT, but usually not when running conditions that run DirectRT before running questionnaires that modify the responses.xls file. I'm not sure if this is coincidence. Also, I noticed a Microsoft Access temporary data-locking file in the experiment directory, which makes me wonder whether Access is conflicting with DirectRT. I am not using Access for anything. Any suggestions?
