For the past two days my internet has been down due to 'electric' storms in the UK. I tried to open a few .PDF files during this time, and they would open but as soon as I tried to scroll down, they froze and said "Adobe Reader is Not Responding".
As soon as the internet came back on, I tried again and they all opened and were 'scrollable'! I never realised that Adobe Reader needed the internet to function before it would work.
Is this normal?
