World Editor doesn't auto open maps

[IronForge]

My world editor does not automatically open maps at first, so I added it as default probram. However it now requires two steps and its getting annoying. When I double click a map, it opens a blank default small melee map and I have to manually open the map for it to work.
please help thanks

Check Preferances in Editor

So does my NewGen, and my Unlimited.
Just so as Day-Elven said, if you has something like that unchecked, check it.
