4x16 lcd

I have a problem with one LCD 4 x 16 Module (from
JHD...lcd-china.com).

This code...

Code: 
lcd_gotoxy(0,0);
lcd_putsf("0000000000000000");
lcd_gotoxy(0,1); 
lcd_putsf("1111111111111111");         
lcd_gotoxy(0,2);
lcd_putsf("2222222222222222");
lcd_gotoxy(0,3); 
lcd_putsf("3333333333333333");

Produces the following output:

Code: 
0000000000000000
1111111111111111
    222222222222
    333333333333

Address Base is specified as following:

Code: 
static unsigned char _base_y[4]={0x80,0xC0,0x40,0x00};

Changing Address Base to:

Code: 
static unsigned char _base_y[4]={0x00,0x40,0x10,0x50};

Result is:

Code: 
0000000000000000

    222222222222
    333333333333

No solution was found on controller datasheet.

MCU is ATMega128 and Compiler is Codevision 1.24.8d

If anyone knows what can i solve it please post.

Thank you
