The address search problem of maps generated from reverse engineered MapSource installation is a different issue, but also related to MDR subfile. In official MapSource installation, each map tile has a MDX subfile for address index info. During map generation, address index info from all selected map tiles are collected and added to the MDR subfile of the output map. But in reverse engineered MapSource installtion each MDX subfile is not fully reverse engineered, so MapSource will not be able to generate a useful MDR subfile in the output map, hence the address search fails.[/QUOTE]
