Just got email back from Nikon saying they found a problem like this on dual processor Macs. It is supposed to be fixed in the next release of NikonScan. (Of course, I'm looking at redoing up to 3000 slides and negs or trying to find and rescan just the bad ones. In one test, there was a 30% failure rate.) The reason I didn't encounter the problem before was the single processor of the iMac.
