Thank you for your reply. I have attached the minidump file (zipped) to the original post.
(Afterwards I checked the sysdm.cpl and the setting was (the Dutch translation of)) "Kernel memory dump", by the way, not Small memory dump, so I've changed that to Small memory dump. Or should I leave it at Kernel memory dump?)
(The Jcgriff2.zip file was created just before the latest crash by the way, whereas the minidump file was created during the latest crash. Is that ok?)
Thanks in advance for your trouble.
