Fiji Is Just ImageJ!

I think your issue is related to this:
For some reason ImageJ1 cannot allocate more than about 1.5 GB of memory on 32-bit systems

I guess the IJ launcher is being too aggressive when it guesses how much RAM to allocate to Java. Some 32-bit systems max out as low as 1.3GB in my experience. :-(
The JavaFX launcher will behave differently so we can fix the problem as part of that work.

thanks. I'm not sure what it uses for the initial guess, or how that works. I did not see a ImageJ.cfg file in the fresh installation... but as soon as I added one, and set the max memory to 1000m it worked fine.
