Drawing Api

1

i am having a problem with the drawing api. it seems like it has some sort of limit to the amount you can draw. when i run this bit of code for about 10 mins it sudennly clears everything that it has drawn so far then continues drawing. i am not sure what to do about this. any suggestions would help.

onClipEvent(load){
    _root.createEmptyMovieClip('drawer',1);
    var color=[0x3a242b,0x3b2426,0x352325,0x836454,0x7d5533,0x8b7352,0xb1a181,0xa4632e,0xbb6b33,0xb47249,0xca7239,0xd29057,0xe0b87e,0xd9b166,0xf5eabe,0xfcfadf,0xd9d1b0,0xfcfadf,0xd1d1ca,0xa7b1ac,0x879a8c,0x9186ad,0x776a8e,/*0x000000,0x000000,0x000000,0x000000,0x000000,0xFFFFFF,0xFFFFFF,0xFFFFFF,0xFFFFFF,0xFFFFFF,0x000000,0x000000,0x000000,0x000000,0x000000,0xFFFFFF,0xFFFFFF,0xFFFFFF,0xFFFFFF,*/0xFFFFFF];
