Why do words sometimes overwrite one another in the title area of the map display screen?
That happens if you have more than one map theme’s box checked – say, November, August and March. ArcExplorer draws the themes in order from the bottom of the theme list to the top. You can see only the uppermost map (March) no matter how many below March (November and August) you have checked. Yet, each map has text that is drawn too. So, even though you can see only one of the (several) maps that are drawn, you can see the text that is drawn for each. And since all maps’ text draws in the same area, they will overwrite each other in upward succession.
