I have run IMAGR on both 32-bit LINUX and 64-bit LNX64 machines using the binaries we ship. I tried with SMOOTH=1,0 in IMAGR and also with SPLIT with 1,0 followed by IMAGR with SMOOTH 0,0. The results are identical to the least bit on both architectures. I don't know what is going wrong with your use of IMAGR but I cannot reproduce it. ERic Greisen
