Actually, I scaled the Skype icon using Graphic Converter. I just looked at the ones included in your plugin and it seems that you already have a 16x16 icon... how come it doesn't line up correctly in the list then?

I am also getting this error. Also, I've uploaded new skype icons that are the correct sizes (16x16 and another 72x72) so the file menu has the correct spacing for Skype accounts. BigBrownChunx, can you add these to the plugin?

Just to follow up, I've posted some images to highlight this issue. http://img2.freeimagehosting.net/uplo...2ba9b47.png
Either the Skype icon is a tad too thin compared with the other icons or it is not being "centered" properly. I would assume it is the former as after looking at the other icons, it seems the Skype icon can be 4 pixels larger in both height and width. http://img2.freeimagehosting.net/uplo...323436d.png

this is a minor bug, but the icon spacing is off in the menus. In the above image you can see it as "Skype API" isn't left aligned from the same spot as other protocol names. This bug is also present in the "Status" and "File" menus.
