did some scans of mkm-1 burned with 716a. scanning @ 8x w/ produced initial spike regardless of what offset I set for initial scanning (188.8.131.52 and 184.108.40.206). scanning @ 4x w/ 4.7.5 stopped at the layer break and wouldn't go on. 4x scan w/ 220.127.116.11 seems just fine. f/w issue or software issue?
