Off course I tried to look into it. Disasm code is complete garbage and unrelated to wmmx. I also tried to see it in visual studio debugger - same problem. However, it works as expected :) When I tried some wmmx intrinsinc asm with ms compiler I believe that in debugger I saw wmmx opcodes instead of some unrelated garbage. ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
