Hi there! I seem to be having a problem with pdf creator. I have windows
7, and the latest version of mozilla firefox as well as the latest
version of pdf , think its 1.7 The problem is that it does not allow me
to wait & collect webpages as the previous older version of
pdf.Please could you assist urgently …


is there no save dialog, does it crash? Pease explain more about how it doesn´t work.
Maybe you have your auto-save turned on?
