Good advice, but on OS X an app should never crash because of low 
memory (however on OS 7,8,9 yes). OS X has a really good virtual memory 
system and running out of RAM the worst thing that should happen is a 
lot of disk activity as the system starts swapping.

Mike, what I was going to recommend is putting breakpoints and stepping 
through all of your startup, openStack, preOpenStack, openCard and 
preOpenCard handlers. Something in one of them is triggering a crash.
