Bentley Map and System Memory

What type of system memory demands does Bentley Map V8i SS1 have?  I have about 10,000+ pipes selected and tried to view them in the data browser and got this error "There is insufficient memor available to handle the requested data set."  I'm running a XP 32bit station with 4GB of memory (yes, I can only use 3GB) and have plenty of swap space so why can't it handle this simple task?

Thanks,

Michael
