Thanks for helping me on this. I'll do a file comparison to find out exactluy what was changed.
Another question to have appeared in connection with this project:
In Promaps for Google I have to set the zoom level for markers and center address options manually after the addresses are registered in the database.
Later, new addresses will be added and some will be taken away, and in this connection it may be necessary with another zoon level and another center address. Is it possible to calculate the optimal zoom level for markers and center point so you don't need to change this manually later ?
