Hm, I can only say it doesn't on my laptop and my stationary. I don't know what causes it then.
Edit 20100212-2046: Now I can see the logo on the site. It looks good. I think the borders between the images are a little bit sharp, especially the border at the hurricane though.
I think hurricanes are slightly off topic to the wiki's subject, but It's your choise. I will only come up with suggestions, so my suggestions to the logo is to make the borders blend better into each other (like only using pictures with black borders), and perhaps to use The Big Dark Spot on Neptune to replace for the hurricane (since that's also a hurricane I think - a pretty big one of them).
There is also a white area under the galaxy, perhaps it could be filled with black. And at last, I think it would be better to have a black background behind the text and the polygons in the right side.
Perhaps the picture with the probe and Earth should be placed in the bottom instead, so that Earth has a more natural cut instead of being cut off by another part of the logo.
That was it. I like the logo though. Well made.
Edit 20100212-2115: Btw, all those systems in the available systems menu... Do you want to create their articles, or is the claimer meant to make their articles? Or should I make articles for some of them? We should aim at reaching 100 articles, so our Sosycrewi can be featured by Wikia.
