two blocks of between group randomization

[Michal]

in that case can i run several input files together (so that i won't have to be present and switch files manually in the middle for every participant)

I'm guessing this needs to be done by running the multiple DirectRT input files from MediaLab? Is this the only way? I have MediaLab and can do this but would prefer to avoid any potential glitches that might arise from jumping in and out of a DirectX environment or in and out of whatever display setting you've established in the DirectRT style file. I'll give it a try. Assume there were no problems if this is the last you hear from me on it.
