I've got a new installation of GoToMyPC on a Win10 client and host. I'm connecting over broadband. When I open a long document and try to scroll down with the arrow key on my client computer, there's a lag so the document keeps scrolling well after I take my finger off the arrow key. The same thing happens whether I connect via the app on my client or via the website. It does not happen when sitting at the host.
How can I fix this?
UPDATE: I tried logging in with another computer (a Mac) and did not have the lag problem. Also, I didn't have this problem until my host computer was replaced with a new Win10 PC.
