John,
If you're running an old TightVNC release on those machines then it's
perfectly possible that you'd see problems with updates - some of the older
releases did have problems with RFB protocol compliance.
Please remember that TightVNC and similar projects are *based* upon VNC,
they're not actually VNC, so if you think you're seeing a problem with VNC,
the first thing to do is make sure you're running an actual VNC release!
Cheers,
Wez @ RealVNC Ltd.
