32 Bit PNG and Transparency

I'm trying to use 32 bit png as images for toolbar control in my windows forms application

They seems to be drawn correctly when I load them in my ImageList Control, but when I select one of them as toolbar button image, transparency is not rendered correctly: all my Icons have some sort of blue "halo" around them

Does someone have some advice for me?

If you are referring to an alpha channel -- this doesn't currently
work with PNG files in .NET.
