This may seem like a strange question. Having moved to a Mac form a PC in the past few months, I have been travelling along nicely with my new format and way of working, so much so I shall not be returning to anything with windows on. However, I have just come across a small problem, not that I suspect it cant be sorted, but I did want some guidance. Having viewed, and in fact created PDF documents with my Mac, I have one which I cannot read. Some of the pages are blank when I know they should not be. I then realised I don't actually have Acrobat Reader on my Mac, not that I know of anyway and this may be the problem ? My question is, should I ? or is the preview facility enough ?
