Thanks A Guy. I opened a PDF file from the internet, saved it to my desk top then opened Adobe Reader 9. In Adobe Reader 9, I went to Open, selected the file I wanted from my Desk Top and up came the file I wanted!!!
Mind you, that was in Adobe Reader 9, not X1 which I still think is not compatible with Windows 7 Home Premium, maybe Adobe have not sorted the problem out yet??
Thanks for your help,
A happy RonBin79 (now 80)
