Ap check printing in ssrs

We are using the AP Check SSRS report in E10. The customer name and address was too high and did not fit into the window envelope. I tried moving the textbox down so that the top line of the company name/addaress would not get cut off, and sometimes this works and sometimes it does not. This is in the footer and in a rectangle so it should be in a fixed position. Has anyone else found a way of locking the position of a textbox so that it always prints in the same spot?

Did you ever solve this?
