When I'm controlling my shared Mac, I ALWAYS have to click twice to be able to single click anything. It's not dropping connection because the mouse cursor moves freely to what I want to click.
I also have the pointer issues as well as issues with it not connection. Is the developer still supporting this software or is he abandoning it? If he is abandoning it, he needs to release the source code so other developers can make it better.
No donation from me.
