Where is the WIP?

27MBs is still a relatively small file, are you sure it is a .PZ3, and not a .PZZ(Poser Compressed .PZ3); also check to see if there is also a .PMD(A seperate file for the  Morphs,) with the same name as your scene file, in the folder the scene is saved in?

O.K. 1 GB... that's 2 - 4 times what is required to surf around, but I bet your system would hold at least 2GB.   I bet you could find another 512MBs or 1GB stick cheap.  My buddy just sold a 512MB DDR PC3200 for like $20...Unless you've actually got two 512MB sticks, and not just a single 1GB stick...My point is that what it is you have is more than likeley two ports to put RAM sticks, but if they're both full then you'd need to sell one to upgrade ;  |.

How big is the Hard Drive?  Virtual Memory is located at Control Panel > System > Advanced > Performance > Advanced.  They say you could/should have 1.5 - 2 X the amount of Virtual Memory as you have Phyisical Memory(RAM sticks,) as long as this does'nt equal more than 2GBs per open application(WIndows counts as an application,) and 4GBs per disk.  So you could set you Initial Virtual Memory to1500MBs - 2000MBs and Maximum to 4GBs.  After you've done so, rebooted, and opened Poser(and/or other applications) the place to see if when you Virtual Memory is kicking in is by htting CTRL-ALT-DELTE(Windows Task Manager) and then clicking the Performance tab; when the PF Usage Graph shows more Memory than the Physical Memory > System Cache reading you know you're using your hard drive as a RAM stick.
