I've used Palm OS Garnet simulator on a PC running windows XP and everything was great. However, on vista, when i try to load a storage snapshot i get the following error:-

'Dynamic heap base address mismatch'
'Can't use the specified storage snapshot file'
I've tried running the sim in windows XP compatiblity mode and as an administrator, also i've tried loading a snapshot saved by vista and nothing has worked. I've also tried all the different RAM sizes and dynamic heap sizes.
Any hints, secrets or solutions?
