An additional check ($this->zoom_factor != 1) should be added to ensure we are
really trying to zoom:
// ABP: check scale
$minscale = $this->map->web->minscale;
$new_scale = ($this->zoom_factor > 0) ? $this->old_geo_scale /
$this->zoom_factor : $this->old_geo_scale * ( - $this->zoom_factor);
if($this->zoom_factor != 1 && $this->old_geo_scale && $new_scale <
$minscale){
return $this->map->zoomscale($minscale + 0.1, $xy_pix,
$this->mapwidth, $this->mapheight, $this->geoext0, $this->maxextent);
}
