Roaming profile problem on WinNT4.0

[IIZUKA D. <ii...@mt...>]

I have a touble with TightVNC 1.2.2 on Windows NT4.0 with roaming
profile.
If VNCserver runs as a service, and someone logon (from local keyboard
or via VNC from remote) and logoff, the logoned user's profile can't
be uploaded to the NT Server.

After logoff the user, I logoned as Administrator and executed
handle.exe (downloaded from
http://www.sysinternals.com/ntw2k/freeware/handle.shtml), then I found
that system still grabbed c:\WINNT\Profiles\user\ntuser.dat, so
updated profile couldn't be uploaded.

It seems that VNCserver.exe and VNCHooks.dll don't close registry
entry HKEY_CURRENT_USER correctly.

Roaming profile works fine if I modify source code not to access
registry entry HKEY_CURRENT_USER.

Same things occured using AT&T VNC 3.3.3r9 and Tridia VNC 1.4.0.0.
On the other hand, Windos2000's roaming profile works fine by default.

Does someone know why this happen in NT4.0, and how to fix with
accessing registry entry HKEY_CURRENT_USER ?

Sorry for my poor English.
