Adding image dialog broken

Hey there,

hope someone can fix this - I guess it is not a big thing, but with the current 
state the plugin is not usable for me.

What steps will reproduce the problem? (Be *specific*)
1. Add an image field to a custom content type
2. Try to add an image via "choose image" button 
3. Close the dialog

What is the expected output?

1. nice looking image dialog

2. when I close the dialog, everything looks like it looked before opening

What do you see instead?

1. I think the image-choosing dialog should be looking differently, for me it 
looks broken (see screenshot I). 

2. When I close the dialog again, my scrollbar is gone. This is because the 
<body> element still has the class "modal-open" to it, which sets overflow to 
'hidden' for the body. So I cannot scroll the page any longer (without fiddling 
in the chrome inspector, which is not cool).

Does the problem continue if you disable all other plugins? (plugin
conflicts cause a LOT of problems, so please isolate the problem)

--> jup, still broken after I disable all other plugins. Dialog looks messed 
up, cannot scroll after closing

Please copy and paste the system information that appears in a yellow
textarea when you click on "Report a Bug" on any CCTM admin screen (this
includes the version of the
plugin, the version of PHP, the version of MySQL, a list of other active
plugins etc.):

Really really hope some of you guys can help me out on this! Love the plugin, 
but without being able to add images it is somewhat useless for me right now. 
Thanks a lot in advance!
