porting problem

[Marshall James]

Hi,
I hope someone can help me out here because I'm almost at my wits end! I'm trying to port a Swarm app from 1.2 to 1.3.1 under Windows NT. I've followed the porting guidelines, and the app compiles perfectly without any warnings. However, at run time I get a status access violation message, caused by the line indicated below with a *

  id <ZoomRaster> worldRaster, populationRaster;

populationRaster=[ZoomRaster create: modelZone];
[populationRaster setColormap: populationColourMap];
[populationRaster setZoomFactor: zf];
[populationRaster setWidth: [epdSwarm getWorldXSize] Height: [epdSwarm getWorldYSize]];
[populationRaster setWindowTitle: "EPD Population"];
[populationRaster drawSelf];
[populationRaster pack];

//create a raster object for displaying cell cooperation and relatedness levels
worldRaster=[ZoomRaster create: modelZone];
[worldRaster setColormap: worldColourMap];
[worldRaster setZoomFactor: zf];
*  [worldRaster setWidth: [epdSwarm getWorldXSize] Height: [epdSwarm getWorldYSize]];
[worldRaster setWindowTitle: "EPD World"];
[worldRaster drawSelf];
[worldRaster pack];

This seems strange to me as the same method works before on populationRaster, but not on worldRaster! I'm wondering if it's a memory problem... as I've been having problems with virtual memory shortages. This used to work before, so any advice would be appreciated. Thanks,
James
