Hrm, I thought the other software required the use of additional hardware.
It's too late now coz... see below...

It might be the latter on the linux box but I have no other processes
running...  Doesn't seem to have happened recently, despite the machine
being loaded ridiculously (ran out of virtual mem).

For the Amiga, I figured it out.  It tends to crash horribly if there was
either bug in driver.c or auto.c.  Once in, it works like a treat. :)  In
any case, I've managed to compile the current stable version of DGD using
some Amiga specific files from that rather old port by Lars Duening.  So
now I have an unsupported binary, er, shalln't go around asking questions
like this again.

Hrm, good point, don't think my swapfile exists. :)
