I noticed the same effect on Windows. What happens is that during a
saveAs the new image name is transferred to the VM - however without any
path information. After the saveAs the image now behaves as if you have
started it with "SqueakVM /NewImageName.image"  The problem can probably
be fixed on the ST side but if you just add the old (i.e. current) path to
the image name in imageNamePutLength() (should be somewhere in
sqXWindow.c) everything should be fine. BTW, that's how I have handled it
in the Windows version.

Hope this helps,
  Andreas
