I have an HP Pavilion laptop, that's about 1 year old, and came with Windows 8. It has been upgraded to Windows 10 Home, Version 1511, OS Build 10586.318. It has an Intel i5-5200U CPU, 12 GB RAM, and Intel HD Graphics 5500. Foldit fails consistently with different puzzles. No matter what, it always fails the same. Foldit works fine when I first start it - until it fails. All Foldit settings are default. I've tried Windows emulations for version 7, Vista, and XP. All exhibit the same failure. After about 5-10 minutes of working fine, something happens, and Foldit stops working, and I get a notice that Foldit has stopped working and Windows is shutting Foldit down. If I bring Foldit back up it will do the same thing. I don't know how to figure out what the problem is, or even who to contact to resolve the problem, except leave a note here.
Thanks for your help.
P.S. I posted a help request on this forum, but now I can't find it, so I'm posting this with a little more information.
