MapGuide Open Source2.5 has a great function is download the markup as kml/kmz file; but there's a small bug need to fix: you can display your kml/kmz using Quantum, ArcMap etc, but it cannot be display correctly using Google Earth. The reason: there's extra common symbol at end of each coordinates values. If you remove these common symbols, it can display correctly. So how to fix this? Thx.
