Thanks, that does shed a light on things. I thought something like that might be going on. I see the following: "32-bit applications can access the native system directory by substituting %windir%\Sysnative for %windir%\System32. WOW64 recognizes Sysnative as a special alias used to indicate that the file system should not redirect the access. This mechanism is flexible and easy to use, therefore, it is the recommended mechanism to bypass file system redirection. Note that 64-bit applications cannot use the Sysnative alias as it is a virtual directory not a real one. Windows Server 2003 and Windows XP: The Sysnative alias was added starting with Windows Vista." Unfortunately I'm running XP 64-bit, not Vista or 7 just yet. The pages you link say that "Disabling file system redirection for longer periods can prevent 32-bit applications from loading system DLLs, causing the applications to fail." What if we add an option to 64-bit Windows Vim to disable the redirection? It could even automatically set the $PATH to include the 32-bit directories before their 64-bit counterparts so that system files continue to load properly, but anything not found in the 32-bit directories will be looked for in the 64-bit ones. And of course all this is *intended* to be transparent to the user :-\ -- You received this message from the "vim_dev" maillist. Do not top-post! Type your reply below the text you are replying to.
