Cannot use ruby installer

[rsilvestre]

When i clic on "add ruby" and select a ruby version to install i always have that : https://www.dropbox.com/s/pgi1m65vnse4eg1/Capture%20d%27écran%202013-11-22%2008.56.47.png

The install many stay on the right of the screen and i can't start the install

I'm on 10.9, using jewelry box 1.5 build 1700 and have xcode command-line-tools 5.0.2

Same issue here. On OS X 10.9.1 on a 2011 15" Macbook Pro. Sometimes if I scale the window smaller, close and re-open I can see more of it but the "Patches" list overlaps (intermittently) the scrollbar. And I can't always scale far enough to see the "Install" button.

Same build of jewlrybox as @rsilvestre and latest version of Xcode CL tools + RVM.

Would be useful if the side panel could be resized. The one time I managed to hit the install for Ruby Enterprise Edition (ree-1.8.7-2012-02) the app crashed after a couple of minutes without installing it.
