(In reply to comment #1) > Possible duplicate of bug 219987. See the discussion there. May be related, but seems to be different as it only happens when opening the pdf in a new tab, and it occurs with Acrobat 5, I am not using 6.

Even though bug 219987 is older, it has more information. *** This bug has been marked as a duplicate of 219987 ***
