[mapguide-users] Mapguide Tile Cache Seeder Tool

[George McLean]

I ran into this problem as well on XP SP2 with MG 1.2

I ended up writing a php script to build tiles. I pass in start and end 
columns and rows and a zoom level as arguments. I then called the script 
from a batch file, stopping and re-starting MG before I called the 
script. It is a hack but it got me through building some pretty big tile 
sets.
