Norbert,
Regarding the Quadro FX cards, nVidia even has a "partner certified driver" for SketchUp. (The driver is currently available only for XP.)
I was pleasantly surprised the other day, when I installed new Quadro driver
Note that, when your system reports that a newer, updated driver is NOT available, you should question from whence that message comes. Apparently, Microsoft is providing this assessment. How do they know? If I check Windows Update, it says no newer driver is available, yet nVidia had one. I suspect that Microsoft will always be behind on it's driver update notifications. Do yourself a favor, and actively search for one on your own. (I have the mobile version of the Quadro FX, and couldn't be happier with this new driver.)
I'm sorry that I can't report that will help Vista users, including Verrou. However, the adviceNorbert provided, regarding 'fast feedback,' is typically the most-effective fix for cursor and marquee-selection problems (XP and Vista, alike.) Turning off 'fast feedback' doesn't slow down SketchUp as much as disabling 'hardware acceleration.' Hopefully, the feedback setting alone should resolve Verrou's problem.
