Stop main window from popping up.

[steven@stevenleeconsultin]

Every time I right-click on the Teamviewer icon to open, "Show Computers & Contacts" the main window pops up.

Every time a session ends, the main window pops up.

I want the main window to never display, unless I chose to open it intentionally. How can I stop this constant annoyance? Other people have posted similar concerns, but in a different group.
