Just ran across an interesting issue. I was debugging a simple for next loop and the values for the loop counter appeared to be out of range. It turned out that when I was hovering the rowcount it's results were being truncated.
Notice the RowCount = 4 in the code window and the rowcount = 40 in the logs.
