Autofocus very annoying on start

[routeconverter]

When I start the program, it tries to download some resources from the web.
There are a lot of errors on these downloads, but it's not the problem here.

For me, that is the problem. And I'm working on fixing the hosting problems.

For each good or bad  download, a message box is displayed in the bottom right corner of the window and each time the message appears, RouteConverter takes the focus above all other active programs : its window comes in foreground systematically. Even if RouteConverter window is minimized.

In Java I'm defining a Window and setting it to visible. This it what it needs.

Could you correct this very annoying bug ?

On Windows and MacOS I don't see the effect that you've described. I think it has to do with the JVM <-> Your Window Manager on Mint integration. No clue, how to fix this.

Maybe you you have a look at the NotificationManager class and try to get rid of the annoying effect?
