No Jim100361, I was blurring some sensitive data in an image for a user manual, then I wanted to highlight an important section of the image in the non blured area. So step 1 I blurred the sensitive data, step 2 I attempted to draw a red rectangle around the completely seperate important information. As Rick Brewster mentioned the selection I made for the blur remained active when I tried to draw the rectangle. Reversing my process to drawing the rectangle 1st then moving onto bluring the data solved the problem.

I was attempting to draw outside. I've re-tried my scenario and can see it does draw as you mention in the selected area. I guess this was not obvious as when you open a fresh image hence with no selection it will draw the rounded rectangle where-ever the cursor is.

Using: Paint.NET v3.5.10 (Final Release build 3.510.4297.28964) Select a rectangular area Effects -> Blurs -> Gaussian Blur -> Radius 6 Select Round Rectangle Tool Cursor changes to cross with rounded rectangle but it will not draw. However if you do this in reverse order i.e. select round rectangle, blur it is ok.
