OK so this is not really a bug I guess. But if you are using the traditional (non copaso) colour mixer to make a palette:

You set the colour of swatch 1. You set the colour of swatch 2. Then you click on swatch 1 so that it is selected, but the pointer in the mixer is still in the colour position for swatch 2. If you go to another tab in your browser, and then go back to the page with the mixer, swatch 2 will be set to the colour of swatch 1.

I suppose its not a huge problem but rather irritatingif you are picking hex codes from other pages.

Firefox 2.0.0.14, windows xp

I have experienced tis too, but I get in in copaso as well. (:

also on FireFox, and I've experienced it on XP and Vista.

I get it in COPASO too. I find it more annoying there because I'm used to making four-color palettes in the standard mixer so this actually helps sometimes. ;)

(Firefox 2 or 3, XP)

Happens to me also, It's really annoying if you're referencing something in another tab..

I have FF2 btw, and i always use COPASO.

yeah been happening to me too switching between the browser and other apps, I don't use copaso though

It is annoying but I make sure to write down the color codes so I can get back to them. Or If I know I am coming back soon I copy to clipboard.

Try double-clicking on the colors ... a little-known feature :-)

yes that is the only way to prevent it happening at the moment.

maybe I'm missing something but double clicking the colors doesn't change this for me?
