problem repositioning tvguide panel (1 Viewer)

[citizenkeys]

in mytvguide.xml, i'm trying to resize and reposition the tvguide panel to fit the background for a high-definition skin.

however, any change to "posY" seems to change the height and not affect the y-axis positioning at all.

below is the code. any ideas how to change the Y positioning?

    <control>
      <description>TVGUIDE Panel</description>
      <type>image</type>
      <id>2</id>
      <posX>90</posX>
      <posY>150</posY>
      <width>1105</width>
      <height>300</height>
      <colordiffuse>60ffffff</colordiffuse>
      <texture>-</texture>
      <animation effect="fade" time="250">WindowOpen</animation>
      <animation effect="fade" time="500">WindowClose</animation>
    </control>
