Global Mapper v24.1

how best to view 3D data, can't seem to center

I have my lidar data centered in global mapper - but when I open 3D viewer I have to scroll the mouse button out to see it come into view. This in turn puts the data at the bottom of the screen and causes difficulty in zooming in to the center. Is there a key / shortcut to get the data to be in the center of the 3d Viewer? Thank you!
