When I try to use the colour change tool, instead of changing the colour (tested using both right and left click) it just draws a line using the currently active colour over any and all other colours.
i.e.: it looks like the colour change tool is behaving as the pencil tool.
I did reinstall an older version which had a properly working colour change tool, but unfortunately, I can't have both versions of Paint.net installed at the same time because part of the installation process is to remove old versions WHICH IS REALLY ANNOYING WHEN THERE ARE BUGS IN THE NEW VERSION!
