I'm connecting to my Snow Leopard (Mac OS X 10.6) from my Windows XP work computer using both TightVNC and RealVNC, and both of those don't give me access to the Option key. So to work around that, I tried using Keyboard Viewer, but that doesn't respond to clicks through these VNC clients. Does anyone have any suggestions?
Keyboard viewer cannot be used to simulate alt, even without VNC. It shows mapping of local keyboard. Keyboard mapping in VNC protocol is a mess.
Differnt VNC client won't affect sharing in any way. VNC server might collide with OSX's built-in one, but not necessarily – you can configure 3rd party server to use different port.
