Hi Steve,
I cannot reproduce that. I changed the code in TREHEader so that the bit is no
set:
// if (props.containsKey("transparent"))
// poiDisplayFlags |= POI_FLAG_TRANSPARENT;
Routing doesn't work in Mapsource or Basecamp.
I've double checked with TreDisplay that the flag is really not set in any map.

cgpsmapper had the option to do 2) without doing 1) which it calls a
semi-transparent map.
I tried un-setting the flag on a transparent map and routing started
working again in mapsource. So it is just the flag that causes the
problem. I don't know what the flag really does.
I also noted from the documentation that cgpsmapper seems to add 32 to
the draw priority of a transparent map, which is something that we do
not do.
