That total unresponsiveness is perfectly normal when starting a render 
of an extremely large output image; POV-Ray needs to create a multi-GB 
temporary file, and Windows insists on initializing this file right from 
the start (rather than initializing only the blocks actually written to, 
as Linux does), which may take several minutes.

Rendering (including creation of the file) is probably still faster if 
you do it in one large render.


There's one other noteworthy caveat with big files: If the scene is 
extremely simple, memory consumption may rise during render as the 
render threads create image data faster than it can be stored in the 
temp file; this can ultimately lead to swapping. (Nothing too serious, 
fortunately; the system will remain responsive enough to handle the 
situation by pausing the render for a while; this will allow image data 
to be tucked away and memory be freed again).
