David, I am not that familiar with the layout code. I ve tried DEBUG_REFLOW but it doesnt compile anymore cleanly. Most of the DEBUGs there also I think they are a bit old. What I would like to know is do we have a test program to see whats going on or at least some clear breakpoints to debug the layout code and find out what it doesnt loaded? (eg a test program that would link with the layout libs only and hence we are going to get a clean pic of what goes wrong).
