Problem Rendering Multi Column

I've added a link to a sample on how my test-column report renders.

Any idea what's happening, while normally previewing the report (column by page) this problem doesn't occur .... The rendering is the same to TIFF

Any suggestion on what is the problem and even better, if there is a solution.

Found the problem, the page width exceeded the normal page width op an A4 page, obviously that gives a rendering problem, as soon i dropped 1 column redering was 'normal'
