Lion's VNC server has a known issue on muti monitor configurations. The mouse pointer may not point to the correct place on multiple monitor configurations where the primary monitor is NOT the left most monitor. To workaround this open up the Displays preferences and make sure the primary monitor is set to be the left most monitor in the configuration. We've alerted Apple to this problem and are hoping that they'll fix this in a future Lion update.
Update: OS X Lion 10.7.3 has fixed the multmon issue.
There is a known issue with OS X Lion 10.7 GM Seed's VNC server. Lion's login screen may appear to stop responding when connecting via Mac's VNC Server. We've investigated this issue and it seems to be a problem with OS X Lion itself. To work around this we've changed the default authentication mechanism in Jump 4.0.3 and later. Jump will now ask for your Mac Credentials instead of the VNC password. Authenticating with your Mac credentials takes you straight to your desktop skipping the buggy login screen. We've also added a configurable setting in Jump incase you want to revert back to the old, VNC password based authentication scheme. The setting can be found in the auth setting field for a VNC server. Setting this to vnc password should revert Jump back to the old behavior.
