Dell 1950/2950 indeed... if there is any way to catch that writing without crashing the syst= em=20 (even to the price of some slowness) I can test it. if not, I can't= =20 because all my available targets are remote administrated and invol= ved=20 with production processes. if luckilly one of them gets free, I'll to apply the latest patch y= ou'd=20 provide me. I may also try it one day I'm close to those machines, = so=20 keep me in the list of up to date patches. --=20 Jean-Daniel Pauget T=E9l: +33 (0)2 33 17 20 16 2, rue Andr=E9 PELCA 50580 Denneville-Plage France
