Modern technologies do not know how to work with multiple monitors (

I constantly work with two monitors, both at home and at work. Very convenient, for example: deployed documentation on an additional, and development environment or something similar on the main monitor. Spending time on switching windows is not necessary, and interferes with work. So, it was necessary to once analyze the information from 1c 7. It was possible to connect to a remote server through the Windows 2008 Server terminal. Using a terminal server based on this OS, you can run applications that look as if you run on your computer, in general, so-called "seamless windows". 1c was launched, I decided to drag it to the second monitor screen. Grabbed the mouse for the title of the window and dragged. The window on the second monitor did not appear ... As soon as the mouse cursor over the header crossed the border of the monitor, the window treacherously appeared on the opposite side of the main monitor. It was necessary to change the role of monitors because of this situation.
The second case was at home. I downloaded one program that did not want to run in Windows 7. Installed on Virtualbox Win XP - the program worked. I put virtualbox drivers on the virtual machine, the so-called “guest OS add-ons”. Enabled display integration mode. The program window, which I launched in XP, refused to be dragged onto the second monitor, treacherously looking like “running on the main OS”. In window mode, Virtualbox runs on a second monitor, reflecting the running program on the display, but not very convenient. Free space on the screen, occupied by the virtualbox interface, is lost, well, you know, when the window in another window is not very convenient to work.

Have you noticed a similar work programs with multi-monitor configuration?
