Imagelist, listview and alpha channel

Hello guys,

I have been reading about this bug in this forum and others but I don't get my imagelist to stop corrupting the images. I have an imagelist filled with png images. These images have their own transparency.

The first time I load the images in the imagelist, and bind this imagelist to a listview, the images are displayed correctly. But as time goes by (I know this sounds weird) the imagelist corrupts the images by adding a blue border to the PNGs and also by lowing the contrast of the images (or maybe adding more transparency to the whole image). I need to use the imagelist since I don't know another way to display images in a listview. Colordepth is set to 32bit which is the actual depth of all the PNG's loaded.

I will be thankful for any links or comments

I've seen the same thing but I just ignore it until it comes time to release my application, at which point I recreate the ImageList from scratch.
