>>1. Often times when I take over the customer computer or server I cannot click on the Windows Start button. That is, I can click on it and the customer says that the menu comes up, but I don't see it. So, the customer has to place some shortcuts for me on the server desktop (e.g. Computer Manager, etc.)

- No experience of this- which may simply mean I haven't had to do it. Sorry..

>>2. Font/screen size. I often struggle to see the fonts/text on the customer computer/server. If I increase the screen size (by pressing on + or - on GoToMeeting), the fonts/text seem to increase but then I have to scroll up and down all the time in order to see the top or the bottom part of the screen.

- If you have access to a 4K monitor or machine, definitely worth a try. Gotomeeting UI lets you scale normal 1080p to satisfactory size with the whole screen visible. By default the UI has quite large panels for webcam but you can squash those out of the way to maximize shared screen visibility.

- If users have 2 monitors, often stuff comes up on the "other" monitor so user needs to drag it to the visible monitor before you can use it. I wonder if that's part of your menu issue? Anyway, I believe Gotomeeting does have setting/s for both monitors to be displayed, but then you'd definitely want the 4K monitor IMHO and you shouldn't need 2 monitors to install most apps anyway.
