------- Additional Comments From vitaliy@kievinfo.com 2006-11-06 23:45 ------- There are several applications that do access SharedUserData structure located at 0x7ffe0000. It is there on all winNT systems.
Also if you load all the Linux libraries into lover 2GB they will stomp over address space required by Windows programs.
This is just reasons why 2GB/2GB split is not compatible with Wine.
