Please either add dual monitor support either by isolating one monitor as the primary display, or support both. Many of us run dual montior now and this has been on the wish list for years and so please allow this in the next version or update. Many of us are getting the span affect while viewing tightvnc. Although all the other software on our systems work with both monitors and our dual monitors are isolated as such. My monitors even have their own task bar so they are isolated but also shared at the same time because i can move items between them and also capture the screen of one at a time if i want.
Tightvnc appears on my primary monitor but the view of the window is as if it is spanning both monitors, the window is split and shows two sections. I have attached an image to show you what i see on my main monitor
