Under Snow Leopard, I had no problems with VNC connections from my Windows 7 64-bit PC to my Mac mini. However, after upgrading to Lion, my Mac mini no longer responds to mouse clicks when using any VNC client on my PC. Oddly, the local cursor is moving and the Mac also responds to keyboard events - I just can't click anything.
I have enabled Screen Sharing/Remote Management and enabled VNC in System Preferences (obviously) and have checked Observe -> Control in the settings.
Has anyone experienced this or have a possible fix/suggestion? Any help is greatly appreciated.
