Hi Bob,

This issue sounds familiar and I think that it has been discussed
on this list, though I cannot find a link right now. Hopefully
Esteban or someone else on the list can provide specifics, but
in the mean time you may want to try using one of Esteban's newer
VMs from the squeakvm.org web site here:
