Hello Scott,
Thank you for the clarification.
Every once in awhile it will let me know that my own machine that I am working from, is online.
Could you please clarify if you mean this notification?

If this is the case, please try disabling the
Notify me when connection is online checkbox in the
Viewer options.
Are other people having this problem, is it really just my configuration alone..?
Unfortunately, we couldn't reproduce the issue and haven't got any other reports on similar issues. Could you please double-check if there is any utility software installed on the Viewer or the Host PCs that uses the keyboard or might have control over the keyboard input?
In addition, please try updating Remote Utilities to the latest
6.12 Beta 2 version - the most recent beta version updates contain a fix for a similar issue where some certain keys (such as Ctrl, Shift or Enter) were not captured by a remote machine. Perhaps, this might also affect the issue you've encountered and help to resolve it.
Version 6.12 Beta 2 is available for the download on
this page. When updating Remote Utilities please make sure to update both Host and Viewer as version mismatch might lead to performance issues and some features not working.
Looking forward to your reply.
