here are my choices:

1 QuickTime Picture Viewer
2 Internet Explorer
3 Nikon Picture Project
4 Windows Vista Preview

1 and 2 look the same
3 and 4 look the same, but nothing like 1 or 2.

It has a lot of great features and it's free!<ul><li><a href="http://www.irfanview.com/">http://www.irfanview.com/</a</li></ul>

If 1 and 2 look the same, and 2 and 3 look the same, then by transitive property doesnt 1 look like 3 too? If so, then how can 1 and 2 look the same and 2 and 3 look the same, but 2 doesnt look like itself nor does it look like 1?

lol i guess you meant 1&amp;2 look same and 3&amp;*4* look the same but nothing like 1&amp;2? =)
