Supremely useful to know that the samples are showing the same problem--nice to rule out any experiment specific causes. Thank you both. This clearly seems for what both of you have reported that this is a different issue than the old 150 item limit issue supposedly fixed with the 2008.1.33c release. So..
Elair2007, with regard to moving your licenses to XP machines, that is no problem at all. Just send John an email to service@ and let him know what you need (no cost of course for this). This goes for you too Kristen if that would offer a short term fix for you.
Elair2007 and Kristen, do either of you happen to have a NON-Lenovo machine (other than your MacBook Pro, Kristen) with Windows 7? We can get you license codes if you want to try it out on them. It would be very useful to know that there is some v2008 x Lenovo, 2-way interaction happening here. If that's the case, it would be helpful to see the dxdiag.txt files from one of each of your Lenovo machines that are crashing. Lenovo makes good machines--I'm quite curious and eager to see this resolved for you.
Please let us know if there is ANY thing else we can do to help in the short term such as getting you codes to use on other machines immediately so that you don't get held up in running your subjects.
