I am having a hard time figuring out the reason to this. I have a macro running that is screen capturing using snipping tool at the same exact coordinates every single time within a web site (a table) in FireFox.
The problem is sometimes it generates screen captures with different hashes (MD5, CRC, all consistent etc). Sometimes the hashes are equal. It's like a box of chocolates. You never know what you're going to get. The content should not vary if the coordinates are the same every time, and the content being captured is the same.
Can anyone explain as to why this is happening? I am trying to make the screenshot theoretically 99% consistent and generate the same MD5 hash unless content within the table had changed.

- .PNG output screen shot
- Same coordinates
- Same webpage
- Different hashes occasionally, same hashes occasionally
