Mission Editor Question
 

Using the Mission Editor, I'm trying to load up any existing scenario missions

I get to the Mission Editor, select Mission → Load Mission at the top of the screen and all I get is a blank (empty) box, yet I can type a specific mission filename with extension in the Filename: box below (without any specific path information) and it loads that mission just fine.

If I choose Load Campaign Mission, I get a pop-up dialog box that allow me to choose a campaign, that lists all the missions in that campaign which load up just fine when selected.

So what gives with the blank box when trying to load up an individual mission? Is there something I'm missing to bring up a dialogue? Shouldn't there be some mission names listed?

You can load single mission only with xxxxx.mu extension.
Just change .ms or .mp to .mu

or

Make test mission, save it and open again

That did the trick! Leads one to wonder why none of the stock missions have the .mu extension or why the programmers would not have seen this during QA tests. At least your answer removed my confusion.

Thanks
