I have export some of my graphics as a tiff format. But surprisingly, they are not openning at photoshop cs3, It will showing me an error message, "end of file error....". But other softwares like photopaint, acdsee opened it perfectly. What is this? is this a problem with coreldraw X4? .

 What would we do without the incredible Os 

Just for the record: I have been sending Tiff images done with both CorelDRAW X4 as well as Corel Photo-Paint X4. Last week as many as 37 vector illustrations, and my client could open all of them. (She is a Adobe user Indesign & PS). She uses Adobe Creative Suite. I dont know if its CS, CS2 or CS3, but all the same she opened them with no problem. And two of my other clients, magazines, could open in their Macintosh and similar Adobe software, with no issues reported. And I also saw the result in printed form in the magazines, and they look really nice.
