Transparency problem with same layer objects

[danel]

Hello,
I love Paint.net, but there is an annoying bug.
I attached a picture to show what is my problem.
As you can see, I have a black coloured Background layer and above that 3 other layers:

1. one with a white circle
2. another with some red text
3. white circle and red text on the same layer.

 

On the left side, I used the Select tool on the red text and drag above the white circle. Different layers, no problem.
But if I use Select on the red text, which is on the same layer as the white circle, and drag above the circle, it's override the transparent background color with the Background layer color. The result is an ugly, black rectangle around the text.
How can I solve this problem? Thanks for all answers.

That's not a bug, that how it should work.

No, it's not. It's overwriting part of the White circle with Transparency, and thus the Black background is showing through.

You should have created a new blank layer on top of everything else and pasted your text on to that layer.

Oh, thanks, now I see the difference between these methods.
So, should I make a new layer for every elements which can cover (at least partly) anothers? 
I remember that in MS Paint there is a Transparent Selection option, which can be so useful. I hope, it will implement to Paint.net also.

Yes. This is a very good practice, especially where text is involved.
