Zooming in UV/Image Editor Issue

After UI changes in the last svn I’m not able anymore to zoom into the UV/texture editor. I’m on os x 10.7.5 with Magic mouse, and until now I got it by swiping up and down (scroll wheel like).
Now this doesn’t work anymore, I tried all possible choices in preferences.

Has anybody the same problem on mac os x, or can suggest a solution?

Thanks, paolo

Thanks to EvilTesla, I solved eliminating the CTRL modifier for Mouse/Trackpad Pan in Image (Global).
