After starting TeamViewer, clicking the Computers & Contacts button causes the window to open. However the window is off the screen and can not be accessed. How can you reset the window's position?
Windows 10?
We have this problem with Outlook on computers with multiple screens. I don't have anything guaranteed, just some stuff to try.
Snap window to position
Hold down the Alt key and press Tab. Continue pressing Tab until TeamViewer is selected, then let go of Alt. Next hold down the Windows Key and press the left arrow once.
Change TeamViewer layout
If you are running TeamViewer 12 you can switch to the new user interface. Everything is in one window and sorted with tabs.
