SF-AI & 4780 useless for B&W negs!?!?

[Jeffrey]

I've been struggling with this software for most of the year I've had it. I shoot 4x5 b&w negs, and cannot get a scan with full tonal range. I am using a Stouffer 21 stepwedge xparency to test, and regardless of any settings I've tried in SF (latest version), I always get the full top third of the scale to be pure white. I tried all film types and brightness settings in the NegFix window, usually ending up with just the 'monochrome' setting, as all the other film type settings give even worse results. Interestingly, I recently scanned the same test strip using the Epson 4870 scan software and got a beautiful tonally even scan across all ten stops just using the default settings! SF is doing a fine job on my color chromes, although I'm now wondering if they are suffering the same issue and I just haven't noticed yet. How the heck do you scan B&W negs with this thing? BTW, I am quite experienced, and use a G5 Dual 2.5 loaded with ram and the current OS.
