You are welcome. I always found that plotting the whole arrays, starting
with the first arrays in the code and then continuing with the later arrrays
until I located the problem, helped me to see what was happening better than
using DebugView or Trace. It is a pretty simple technique but very
effective, maybe it would make a good little "Debugging Your Code" lesson in
the Users Guide. 8 - )
