Pasting partially transparent image into MS Word: consistency

[Antediluvian]

Greetings.

 

An image with transparent background, two copies pasted from paint.net to MS Word a minute apart, one copy has proper transparency (page background visible), one is filled with white. I believe there's a trick to control transparency, but what is it exactly? I didn't use any tools beside the conventional Ctrl+C/Ctrl+V, and definitely didn't fiddle with image format in MS Word after pasting it.

There's no trick, the clipboard is just a cranky thing in Windows, to hand-wave a summarization of the many long battles I've had with it.

 

Also, you didn't specify which version of Word you're using ... make sure you're using the latest. Same for Paint.NET.

A random, albeit useful bug. Defeat accepted.
