Please excuse my ignornace, but I don't yet understand what "go32v2"
means...I see this term used in the FPC documentation in connection with
platforms, but I've never heard of it.  Is it a processor?  Or an OS? 
Or what?

I am running entirely in graphics mode and am using the graph unit to
accomplish this.  I am creating state-of-the-art graphics that can be
manipulated by the user via the mouse.  I simply need to be able to read
mouse events (and also to change the mouse cursor).  The application I'm
creating must run on Win32, Linux and Unix (and Mac when FPC is
ready)...with separate compilations for each platform as needed.  

The units in the RTL are system independent, which I greatly appreciate.
 I also greatly appreciate the graph unit's capability to select the
highest resolution possible for any machine.  However, the mouse unit
offers only "character" granularity resolution which won't work in a
hi-res graphics environment...I need the mouse resolution to be at the
pixel level, as it is in any modern GUI.

How can I achieve this?
