I have 2 pdf files.
I compared them with WinMerge, BeyondCompare, and even compared their checksums. They are exactly the same to me in every way.
If I open them with Adobe Reader in Xp, and compare them with my bare eyes, they look the same.
But!!! If I open them with Adobe Reader in Win7, and compare them with my bare eyes, they look very different!(particularly border width).
Here are the 2 pdf files I'm talking about:
And here is a screenshot of the 2 files. The one on the right side has thicker border if you look carefully. Remember, they have the same checksum.
I would really appreciate it if any clues. Thanks in advance.
