Problem with Appearance

[neopiper]

I don't know why my icons on the top menu bar in ubuntu 11.04 are not well displayed. I went to the appearance to select a new theme and I found that it is not what I expected.

I don't have the options for customization I had before. My window looks like shown in the attachment as well as the icons I'm talking about (dropbox looks weird).

Any ideas how to solve this?

Thanks in advance

Obviously, you aren't running Natty 11.04 anymore, but Oneiric 11.10, or at least Gnome 3 (if possibly installed through PPA); use "Gnome Tweak Tool" for that, it's in the official repos (or in the possible PPA), and will show up as "Advanced Settings" in the menus/Dash.
