Image loses transparency

Image loses transparency
I have a very strange behaviour here.
*) Open the image "Ok.png" - you'll see there's a small green triangle on the right.
*) Mark and delete a bit of the triangle.
*) Save the image (I checked the 3rd (gamma), the 5th (resolution) and the 6th (time) checkbox).

When I now open the saved image in a different viewer (I use the picasa viewer because this viewer shows the transparent areas nicely), the image is still transparent.

*) Delete the rest of the small green triangle on the right.
*) Save the image.

When you now open it in a different viewer, then suddenly the background isn't transparent anymore. (It's then like the 2nd attached pic - Fail.png)

HELP!
Thanks!

RE: Image loses transparency
1) works for me and 2) your "Fail.png" has a transparent background for Gwenview and my three web browsers: Firefox, Chrome, and Konqueror. To test in your browser:
Code:
<html>
<body>
<div style="background-color:#c0c0c0;">
OK: <img src="Ok.png"
<br>
KO: <img src="Fail.png"
</div>
</body>
</html>

RE: Image loses transparency
Hmmm... then maybe it's a bug in Picasa.
Thanks a lot!
