--- Comment #4 from Niels niels.emmersen@pkf-it.dk 2008-02-16 03:53:12 --- I've updated my hardware, and the problem is now gone (with 0.9.55) or has at least changed character.
When I reported the bug I was on a standard x86 machine (AMD XP 1800+) with a Nvidia 5200. I couldn't get DAZ to work under 0.9.54 or 0.9.55. I updated to a Intel Q6600 with a Nvidia 8600GTS, 64 bits. Both machines run Gentoo.
I kept my .wine folder, but installed 0.9.55 on the new machine. When I start DAZ, the content window is still obscured as reported, but doing an empty render clears it. That's good enough for me!
