No Windows here, but see below > (Yes, all suggestions above imply suspicion about the hardware itself rather then the driver) Well, it used to crash some industrial board (I believe it was some Boser, HS-series, with this card in a PCI slot of its backplane). So you're not alone in your suspicions (OTOH, that board was known to misbehave itself). I have no particular need for that card, so if someone wants it for testing I gladly part with it (and if you happen be in Germany, I'll just mail it).
