I have moved all the home machines up to Windows 7 64 bit and don't see this issue.
Can you tell a little more about this one? How would I duplicate the issue?
Here I installed FireFox and Adobe Flash and it's working.
I have a ACER notebook with 64-bit operating on Window 7 version and everytime i tried to log into a web page with picture or video (infact most of the websites) i encountered a 'prompt message' requesting for a ADOBE FLASH dowload and everytime i tried to download this flash, I am not able to download it at all.
Would someone be kind enough to explain & clarify please !
