Custom Controls help (solved)

Hi there! I'm working off of the "flatpano" skin. I have the following in a new xml, and it is mostly working:

<layer name="btn_in" keep="false"
  url="zoomin.svg"
  align="right"
  x="20"
  y="-40"
  ondown="set(fov_moveforce,-1);"
  onup="set(fov_moveforce,0);"
  />


<layer name="btn_out" keep="false"
  url="zoomout.svg"
  align="right"
  x="20"
  y="0"
  ondown="set(fov_moveforce,+1);"
  onup="set(fov_moveforce,0);"
  />


<layer name="btn_fs" keep="false"
  url="fullscreen.svg"
  align="right"
  x="20"
  y="60"
  onclick="switch(fullscreen);"
  devices="fullscreensupport" />


<layer name="defaultskin_buttons" visible="false" />

For some reason, the full screen button is much larger, and tiling. Any idea why this might be happening?

I tried messing around the crop, but I just wanted to post to make sure i'm doing this right in general before i dedicated more time to it.

One other thing: I just noticed something when I tried to take a screenshot, that the shift key zooms in, how do I disable this?

Thanks so much!!

Update: I fixed this by simply not including "defaultskin.xml" in "pano.xml"
