How to track errors when DR crashes?

Dear all,
Newbie question and looking for a way to become a useful Beta Tester: I'd like to play with Fusion a bit and certainly use the Effects Library in Edit, but as soon as I do something with those, DR bombs out without any messages. I can of course "Create the Diagnostics Log on Desktop", but the information there most likely doesn't show what it's up to immediately prior to crashing. I have the idea it is either trying to use a non-extisting (OS) graphics library or perhaps something with the GPU, but I can't put my finger on it. Any suggestions on how to dig deeper?
