Hi There,

I am using medialab to run my experiment. The version I have is 2010.2.19

In my experiment I have a experiment intro file, then matrices of pictures (matrix = 9x9 picture) that I had created in DirectRT and embedded in medialab and finally a demogrpahics questionaire.

My question is when I run the study and the part where the direct RT matrices start I am able to go through the matrices, and make the necessary judgements I need to on the keyboard (i.e. pressing A and K depending on whether a matrix generates a particular emotion or not. However, after about 5-10 minutes, medialab freezes on a matrix and I cant press anything to move forward hence I hit ctrl alt delete to close the program and then I see that the resolution of my entire desktop has changed as well. I dont know whats going on can someone tell me a quick solution to this problem

thanks
