5x16 LED Marquee Phantom LEDs Turning On

i have built 5x16 led array make marquee sign. replicating http://www.nerdkits.com/videos/ledarray2/ not many leds (unfortunately  ).

there 5 "row wires" , 8 "column wires". each column consists of 2 led columns. putting high through column , low through row turns on left side of each coulmn. reversing high , low lights right side of column.

i found wonderful charlieplexing class on wiki , have made work setup. (http://www.arduino.cc/playground/code/charlieplex)

here problem lies. when using class , cycling through 80 leds, there on pin 0 come on , flash seeming randomly. also, other random pins faintly glowing. know fact isnt wiring/electrical issue because if cycle through hard way, doesnt it. in code causing them flash.

here code:

code: [select]

#include <charlieplex.h>

#define number_of_pins 13

byte pins[] = {0,1,2,3,4,5,6,7,8,9,10,11,12};
charlieplex charlieplex = charlieplex(pins,number_of_pins);

charliepin leds[80] = { {0,12}, {12,0}, {1,12}, {12,1}, {2,12}, {12,2},
                       {3,12}, {12,3}, {4,12}, {12,4}, {5,12}, {12,5},
                       {6,12}, {12,6}, {7,12}, {12,7}, {0,11}, {11,0},
                       {1,11}, {11,1}, {2,11}, {11,2}, {3,11}, {11,3},  
                       {4,11}, {11,4}, {5,11}, {11,5}, {6,11}, {11,6},
                       {7,11}, {11,7}, {0,10}, {10,0}, {1,10}, {10,1},
                       {2,10}, {10,2}, {3,10}, {10,3}, {4,10}, {10,4},
                       {5,10}, {10,5}, {6,10}, {10,6}, {7,10}, {10,7},
                       {0,9}, {9,0}, {1,9}, {9,1}, {2,9}, {9,2},
                       {3,9}, {9,3}, {4,9}, {9,4}, {5,9}, {9,5},
                       {6,9}, {9,6}, {7,9}, {9,7}, {0,8}, {8,0},
                       {1,8}, {8,1}, {2,8}, {8,2}, {3,8}, {8,3},
                       {4,8}, {8,4}, {5,8}, {8,5}, {6,8}, {8,6},
                       {7,8}, {8,7} };

boolean singleon = false;

void setup() { /* nothing */ }

void loop(){
 
 if (singleon) charlieplex.clear();
 
 //cycle through 80 starting @ top left going right
 for (int i=0;i<80;i++) {
   charlieplex.charliewrite(leds[i],high);
   delay(15);
   pinmode(leds[i].vcc, input);    //2 inputs less calculating time clearing 13 pins
   pinmode(leds[i].gnd, input);
 }
 singleon=!singleon;
}

hello.

could identify index /led causes flashing. ?

i author of library, unfortunantly have not tested above 3 lines.  

i'll gladly fixing error/bug.


[edit]

it better use other pins 0 , 1. serial rx tx.

what do?
[untested code]
