Hi Jim-

Glad to hear it.

The problem is that the dislay does not get added to the window
until it has data.  Transparency is dependent on the order in which
displays are added (last one will be transparent).  In your case,
it sounds like the radar gets added before the background, so 
transparency no longer works.  

This was fixed in 1.3b2 for Level III radar and satellite imagery by
adding in dummy data immediately and not waiting for the server. 
We'll look at doing this for all displays.  Also, in 1.3b2, you 
can use the View->To Front menu option to bring the radar to the
front (which removes and re-adds the display), thereby enabling 
transparency.  I'll add this note to the FAQ and the existing
Bugs list entry on transparency.

Keep them coming - just send them to address@hidden 
instead of us directly.  They are less likely to get lost. ;-)
