Whenever I try to edit a png file I get an error message.
Using the latest version MyEclipse 10 M1
I am using Mylyn Plugin to open an attachment residing on our remote task repository server.
I can open jpeg files but not png. I checked the remote server and it is returning the correct content type image/png.
The server does however require authentication to view the image but again I can view jpeg files.

Sam,

Sorry you are seeing this issue. I can replicate it at my end and will file a bug report for it. As a workaround, you can open the image file with the system editor.

If you have other issues please let us know.
