Subject: Re: [FD] Discussion: Teamviewer "Feature" or "Bug"?

Good Afternoon,
This sounds more like a feature than a bug as it is present is most "live
support" software such as LogMeIn Rescue, Bomgar, etc. Most of these
applications have controls to limit clipboard sharing. Some even have
restrictions on bidirectional sharing.

There are a number of legitimate uses for Shared Clipboards such as sending
long URLs, pasting command line arguments and more.

In hindsight, techs who use Live Support software should be conscious of
what may be contained in their clipboard as it is possible that they could
accidentally expose confidential information that they may have previously
pasted into an email.
