My elf file is about 200Mb and it will not load. Ozone consumes most of my system memory (i have 32 GB), as much as 21GB! This issue was marked as resolved in version 2.56a, but in 2.56e it is certainly an issue for me. I have a core i7 running Windows 7 Enterprise with an 512GB SSD and 32GB of memory. I can't imagine anything taking so long to load a file or consuming so much memory. When trying to load same file under Ozone 2.52b, after 15-30 minutes, Ozone crashed.
