X3: Strange Scroll Zoom Behaviour? - ## Please Ignore - moved to X Series Forum! ##

Hi All
 
Is anyone else getting this behaviour when using the scroll zoom (eg Alt + Mouse wheel)
 
If I am zoomed in on a track further down the screen (eg track 20) and try to zoom out using the mouse scroll wheel the screen jumps to the first track so I have to zoom out and then move down again
 
I am sure this should be just zooming out from where I am working?
 
Is anyone else getting this or is there a change in method I am not aware of?
