Dell 1950/2950 indeed... if there is any way to catch that writing without crashing the system (even to the price of some slowness) I can test it. if not, I can't because all my available targets are remote administrated and involved with production processes. if luckilly one of them gets free, I'll to apply the latest patch you'd provide me. I may also try it one day I'm close to those machines, so keep me in the list of up to date patches. -- Jean-Daniel Pauget Tél: +33 (0)2 33 17 20 16 2, rue André PELCA 50580 Denneville-Plage France
