I'm only a customer too. But I can understand your frustration.
I tried opening the pdfs on a mac on vista on firefox, safari, opera,
ie explorer, blah blah.
I have written up this issue many times and still nothing has
happened. But I'm sure it is early days and they might get onto it
as some point.
I was told to right mouse click on the link so that it downloads.
sometimes this works and sometimes it doesn't. So you just
have to hang in there and hope they address it for use eh ???
Then you will have to struggle getting the bloody program to work
but have a look at my posts they will help you get up and running.
There are a lot of kind people in this forum that will help you if
you are new to it all like me !!!!
