Help with a marquee.

Hi I made this marquee program however, I am having trouble getting all four marquees to line up correctly. Basically I want the the 4 marquees to line up on the four sides exactly so they intersect. Three of them look good. With fourth the marquee does something funny this is illustrated if you change the border color of the "up" marquee in the program. Help and insights would be appreciated.
Here is the program, it is computationally expensive so it may take a few seconds to load.

Te code:

Expand|Select|Wrap|Line Numbers
