Hi, we are having the same problem as well. Our lab just got new LENOVO desktop 64-bit Professional computers with Windows 7 on them and we installed Media Lab 2008 1.33c and Direct RT version 2008 that works with Windows 7 compatability this fall. We have been experiencing a crashing/screen goes blank problem that is similar to others had before the 1.33c fix that I was reading about on another thread. The difference, however, is that it does not happen after 150 responses, it seems to happen at random times during the session. We are running two different experiments in our lab and both experiments are having the same problem in all conditions and on all 4 computers that our lab has. Sometimes the problem happens 4-5 minutes into the experiment, and other times it happens in the middle, or with only 5-6 questions before the end. When the screen goes blank we need to use the task manager to break out of Media Lab as well.

We toggled the windows xp compatability mode in the properties for medialab, but there has been no change in frequency of crashing in the last 3 days. We tried to use windows XP mode to run the media lab out of, but the application within xp mode prompted us to license those versions as well, as if they were running on a different computer.

We were wondering if there was a fix that we could install for the crashing problem in Windows 7. Alternatively, we were wondering if we can't get this issue fixed, if there was a way to import our license on media lab over to the xp mode version on the computers, or receive codes from the sales department that would work in that fashion.
