[ka-Map-users] initialize to a certain position

[Hermawan Sutantio]

Dear Paul,

I followed the code snippets to place a marker in the map.
I discovered that the marker changes position as I zoom in/out. It 
doesn't stay
at the right coordinate at large scale. It becomes more accurate in the 
smaller
scale.
Has this been observed by anyone who has tried the same code?
Thanks.
