I have experimented heavily with this.  Commenting those out does give 
nice results, except that sooner or later some artifacts get left on the 
screen.  I have so far been unable to completely fix this.  I rewrote it 
significantly in version 0.4.4 to handle most situations.  Hopefully I can 
figure out the remaining problems and then do what you did below.

I have experienced the most problems with the 36 environment.  Also, using 
SEU and bringing in another source member in the bottom half of the screen 
results in a line being left.  Also, I believe the ruler doesn't erase 
properly if you turn that on.
