Hi,
I lately switched from ij1.38x to ij1.41o and from a 32bit a 64bit mac (MacOsx 10.5.4, java version "1.6.0_07", 32GB RAM).
Now I encounter frequent crashes when repetitively loading list of about 20 images (1024x1024, jpg) and arranging them on the screen using the code below:
for ([members of list]) {
        open([member]);
        DEFINE_NEXT_POSITION_AND_NUMBER(6);
}

function DEFINE_NEXT_POSITION_AND_NUMBER() {
        wait(1);
        if (nImages > 0) {
                previousImage=getTitle();
                selectWindow(previousImage);
                getLocationAndSize(x, y, width, height);
                numberOfImagesInX=floor(screenWidth/width)-1;
                numberOfImagesInY=floor(screenHeight/height);
                posX=x+width;
                posY=y;
                remX=(nImages)%numberOfImagesInX;
                remY=(nImages)%numberOfImagesInY;
                if (remX==0) {
                        posX=0;
                        posY=y+height;
                }
        }
}

I am starting ImageJ from a terminal using:
relPath=[predefined];
java -d64 -Xms2000M -Xmx24260m -Dj3d.noOffScreen=true -Dplugins.dir=$relPath/ImageJ/ -jar $relPath/ImageJ/ij41o.jar

Always I get:
"Invalid memory access of location 00000000 rip=807f6b39"
after a crash as feedback in the terminal.

The console gives me tons of more or less useless information. Here an except of the most informative ones:

conclusion: something with thie window handeling gets completely wrong. Can I do something, to avoid this crash?
BTW: the same behavior I encaounter using Fiji(Dresden).
Thanks in advance,
