Thanks Pat. This does put a different complexion on everything. I think I
have no clear reason for not sticking with Foxit, since I haven't actually
been affected by any of these problems - but the seeds of mistrust are sown,
here. Better to know, and decide, than to risk missing that there was a
decision to make.
(This reminds me somewhat of installing the BT software that came with my
broadband package a couple of years ago. There was no actual spyware
involved as far as I know, but during the following few weeks I gradually
uninstalled virtually every component of the stuff the disc had installed by
default. About 99% of it was unnecessary clutter.)
