All,
It's been 6 years since I first posted on this problem and guess what, it's still there...
I understand that there may be programming difficulties, but this is a fundamental problem. It is a critical tool for map making involving the natural environment. I am again experiencing refusal to trace, either at all at any zoom level, or causing ArcMap to crash. Like all the other instances it develops in one specific part of a map where it resides forever, regardless of restarts, updates, or making a cup of tea.
ESRI: please explain why I should continue to pay or maintenance when what to me is a fundamental tool for ensuring correct topology and efficient mapping does not work and cost me time and money.
Thanks.
