Connectors > Hotspot Image Connector > Hotspot > text when clicking on a hotspot

If I use Connectors > Hotspot Image Connector > Hotspot > text when clicking on a hotspot, I would like the new popup window to appear at the top of the screen and not in the middle. Sometimes I also have longer images in text fields that are now out of view at the bottom.I prefer maximum high, ou using % for this popupscreen.
