Yes, a copy (like viewer.pdf) would then be held in the browser's cache. 
I have the pdf add-on disabled because it obstructs my browsing habits. 
But I tried this out just to see how it felt (using AR8 in IE6): 
Lilypond still got blocked, so presumably the cache was bypassed.

I had thought that the automatic reloading offered by Sumatra would let me 
eliminate the mouse drudgery *without* using a script. 
But the Lilypond conflict prevents that. 
And now I see that automation makes important the secondary things which I 
hadn't really noticed when in manual mode: 
- the sync problem I mentioned 
- keeping the viewer window on top (or not). 

I have now tried out 3 different methods: 
A  using automatic reload, via a copy as I outlined. 
  This needs an annoying initialisation phase to start up the viewer. 
B  closing the view but not the viewer and then reopening the view in the 
  same viewer instance (as I did manually). 
  This needs no initialisation but offers no other advantages
C  using taskkill and start, as you do. 
  This puts the viewer window on top by default. 
At the moment I favour C. Here is my version (simplified) , which also copes 
with the log getting out of sync -  dummy.log says "nothing logged".

start notepad 1.log

Sumatra solves the Write problem but the Delete problem remains. 
On the other hand, this has now become almost irrelevant to me because, 
in automatic mode, I want the pdf deleted before Lilypond is started. 



Someone might just have happened by and concluded that also on Windows 
Lilypond should not delete (or at least not abort when delete fails). 
Maybe the "SLopUF" warned them off. Or maybe it's

cecause cackend clogs can ce a cit coring.
