[ka-Map-users] tiles desappears

[Pg]

The effect you describe is similar to the effect you can see in a map
without a __base__ layer if you unchech the lowest layer in the legend
(the first in the .MAP file), or when the same layer is not visible
due to a ka-map scale out of the layer scale bound.

Try putting on the .MAP file a first layer always visible, without
scale restrictions.
