Flashing firmware with Nforce-ide-drivers

I have noticed a strange thing. When I flash my Benq with the Nforce-ide-drivers installed the flash “hangs” for about 15 seconds near the end. Then I get the message that flashing was succesfull. But if I flash the drive with the standaard ide-drivers installed it flash like a charm. No “hang” happend and flash very smooth. Maybe this is the reason reason why many people suddenly have those huge spikes at the end of a burn.

I noticed when I last flashed a similar behavior, a complete system freeze for around 20 seconds. I was close to hard reset when it came back. I’m running Nforce but I don’t recall that happening on previous flashes and I’ve had Nforce for a while.
