I had this too while making some changes to VNC for our local situation (we
used tightvnc as a base).

Every time you log in, log off and lock workstation a desktop switch occurs.
For some unknown reason (to me) a winvnc call to the win32 api
(OpenInputDesktop) fails under some circumstances. I found that there could
be 2 causes for this:

- Something goes wrong when repeatedly installing, stopping and starting VNC
  without rebooting. A reboot helps.

- Calling CoInitialize on the client thread. I have no idea why. If you (or
someone
  else) made changes to the source code, remove this call (and other COM
calls)
  and the problem goes away.

Do you have other software installed that might interfere with VNC? (e.g.
other remote control software).

Hope this helps,
Daniel

Subject: logoff breaks connection


Hello Everyone,

I'm trying to prepare for installation fo WinVNC for our company and I'm
busy testing. I run into the following problem: I got WinVNC installed as a
server, but everytime I am connected and logg off (remote) the connection is
broken. Then I have to reconnect to login again onto the NT Domain. After
the script has been run the connection is broken again. So again I have to
reconnect once more to continue working remote.

Does anyone know what the problem of this can be??
