debug dx9 != release dx9

Ok thanks. Problem is now identified :
It only appear in the release version, when launched out from visual studio.

Ok, I fixed the crash, your ufo file now work properly.
The particles at 0.0.0 should also be resolved by the same fix. It's ok for me, if you can test it on your conf, please.
Thanks.

I will check and get back to you this evening.

You fixed it, man. Both bugs are gone. You've made the world happier!
Many thanks.
