Hi all, I'm importing data from pdf documents on a web site. This works well most of the time. But for a few of the pdfs, Mathematica "barfs" and does not return either the "Pages" or the "Plinatext". (I am only really interest in the "Plaintext".) Instead it produces error messages such as "Expected PDF object" and "Expected array operator argument", etc. Here are actual examples. First, one that works fine: Import["http://www.cmegroup.com/daily_bulletin/Section09_Interest_\ Rate_And_Energy_Futures_2008017.pdf", "Rules"] Next, one that does not work fine: Import["http://www.cmegroup.com/daily_bulletin/Section09_Interest_\ Rate_And_Energy_Futures_2008016.pdf", "Rules"] Finally, one that really bums out Mathematica (it produces a Runtime error from Visual C++): Import["http://www.cmegroup.com/daily_bulletin/Section09_Interest_\ Rate_And_Energy_Futures_2008022.pdf", "Rules"] Note that Adobe has no problem opening and reading the ones that give Mathematica problems. Presumably, this behavior is a bug. Have others encountered such problems with other pdf files? (FYI, I'm using version 6 for Windows.) --Mark
