Wrong colors after changing background

[gr8]

hello

i have a gadget on my windows 7 desktop .

now i changed the background to transparent using paint.net, latest version.

for some reason some of the colors (/text and icons) became a sort of rosa color .

can anybody give me some advice, why this happens and how i can get rid of it?

many thank for your help.

edit: i have the same problem with another gadget

edit1: here is what i did...

1. open the picture in paint.net

2. changed in the layerproperties the opacity from 255 to 122

3. saved the picture as 32-bit png file

im no expert, but are you running the 64 bit version? it would make sense that colours in a 64 bit pic would change if saved to 32 bit

any other ideas?

That doesn't make any sense whatsoever.

My hypothesis is that the gadget program is expecting the PNG to be stored in "premultiplied alpha" format. Paint.NET -- and in fact the PNG specification itself -- only uses "straight alpha". I'd look into the documentation (wherever that is) for the gadget stuff to see if it mentions anything like that.

thanks for your answers.

it seems that the problem lies with the gadget itself and how they are build (how the background pic is shown).

i'will investigate and if i find a solution, i will post it here.
