Late response to Alston, I don't use screen sharing. Never have. Doesn't mean I won't. Just something else to deal with.
As for Chrome Desktop, I have used that a few times where my son was walking me through an install. It is more secure than many of the screen sharing programs but only use with people you trust.
Tyler raises and interesting point about privacy. Depending on how you use screen sharing privacy may be an issue. If you are completing the application where PHI
, SS, bank info, etc is involved you need to know just how secure the program is. Often the "free" services are offered because they are "listening in" on your program and may use information to generate revenue for them.
I love Google and all the "free" stuff they offer, but it comes with a price. The same is true for any "free" software you get from different sources.
You really need to ask yourself, "Why is this free?".
