Missing files: sun_icon2.png and outline_icon2.png

[FastThenLeft]

I thought I might work on some of the bugs/enhancements and when I went to build it, I found that there are two missing files in the repository:
sun_icon2.png
outline_icon2.png

That also made me worry that the repository might not have the latest files. I didn't want to start debugging old versions.

Could you please check that everything is up-to-date?

Sorry for the delayed response. Thanks for looking at some of the bugs.

When I run without the icons it starts up and defaults to the labels. But I agree that the two files were not checked into the master branch. I just pushed them to the repository.

All of the icons are in a directory called images. At run time they need to be in the same directory as the jar or main class.

Thanks Chris! Java isn't a language I know, but it's close enough to C++that I should be able to pick it up quickly. Thanks! -David, N9KT

Ok, sounds good. I am using Eclipse as the IDE. That may make things easier. If you need instructions or help to compile I am happy to supply. The key is to make sure that the dependencies in the lib directory are included in the class path when you compile and run.

I too have this same error (and a bunch of friends that have installed the program after I've shown it to them). It happens when the Keps are older than 24 hours. I can trigger it reliably if I "touch" the nasabare.txt file and make it 25 hours old, and then run the program.

In my testing, it also seems like if the keps are older than a week, then it works.

I've started to debug it. Here's the output in case it's evident to you. The error is triggered by line 188 of SatManager.java. The error creates a zero-byte nasabare.txt file and therefore the program displays no satellites.
