Well, for me I can click yes or no on the message box, it always shows up when I redrop a file on the Edit page area.
I played with resizing the photo. When I set the largest dimension to less than 3001 pixels, it works.
No big deal, I'll live with that, I don't print posters.
Thanks anyway.

Version 2009.269. When dropping file on the page I get the message in the attached file. I want to answer NO cause I want to print on one page with freehand placement. Answering yes or no does not change anything. I used to be able to do it. What doI miss ? Thanks.
