You need to resize every table for arcaderender mode. Press the scroll lock key, that will give you options for position, scaling, etc. Page up and Page down keys toggle between the settings. Use the 2,4,8,6 keys to adjust settings. Use the enter key (i think) to move the image center to corner (do this first to get more of the table on the screen). Also, I forget what key it is...but if you hold it down while you adjust, it speeds it up. Much better to move in large increments that way. I will check to see what key that is.
MOST IMPORTANTLY...SAVE THE TABLE in the editor or your changes will not be there when you go back to play.
