     This is a guess; but, it fits the observations made so far: AWGS
crashes on some systems more than others because it is a large
feature-rich system which, aside from having its own bugs which may
relate to specific memory setups, is vulnerable to OS bugs and hardware
glitching.

     For example, the presence of NDA's and Inits will change the way
AWGS is located in memory. Even if the NDA's include no known problem
causers, just their presence and the need to depend upon Mem Mgr to
handle placement of AWGS and resources is one important variable.

     Many users have IIgs's which include power-sucking plug-ins. If
they have not taken the usual steps to eliminate noise on the power
rails, their machine is virtually certain to have noise glitces which
can mess up memory, interfer with processing of interrupts, etc.. With a
large system like AWGS, the odds of hitting messed up memory or having
an interrupt bomb are greater.

     Does the presence of a RamFAST increase the probability of an AWGS
crash? The answer is probably "Yes". But, then, it would be the same for
any hard disk interface. Cards like Second Sight and PC Transporter
should be even worse. Any large complex software system which depends
heavily upon OS features is going to be more crash-prone as OS-user
hardware/firmware/software complexity increases.

     The more things there are to 'go wrong', the greater the
probability that one of them will.
