not sure what you mean by "HAS TO BE CLICKED to reset the app" I can leave the pop up up on both pcs and still use TV fine.
If you set the app up the wrong way it does not continue to listen after you disconnect, perhaps that was his issue.
Slider, you might be correct. I am not using TV but just want to reiterate that I was using my Android phone, and using my master password to connect to my home computer(s). After I would disconnect, that dialog box popped up. Then I couldn't remote connect any more, unless and until someone at the home computer would physically move the mouse and click [okay] on that pop up.
I am currently using TightVNC and it serves me well. If I ever get a chance to experiment again, I will reinstall TeamViewer and attempt to make sure everything set up correctly, and not use the master account password to log in, plus actually try to log in from a desktop, and not just my smart phone.
I consider the matter closed. Thanks to all who gave input on this topic.
Just as a last note to any that may find this looking for an solution to that issue, it sounds like you were using the instant customer version and not the full version. That "one use" behavior is the instant versions design. Anyway it's good you have a solution.
