    SK> Just close the Acrobat Reader or whatever.

or even better: Close your OS (MS Windows) and start using a
better one. 

E.g., on all Linux versions I know I can write to files open in
acroread (or any ofther of the several alternatives on Linux)
and then "reload" the file inside the PDF viewer.
