If you toggle Full-Screen mode in the Remote Desktop Connection (RDP) client software by using the CTRL+ALT+BREAK key combination, the RDP client software leaks memory. The client desktop is not refreshed correctly, or you receive an "Out of Memory" error message. For example, the desktop wallpaper may not be repainted, and icons may not be shown correctly. When you quit the RDP client software, the memory is released and the computer works correctly. You can toggle the view mode from 10 to 70 (or more) times before the problem occurs.
The RDP client software leaks memory when you switch between the session and the desktop. This exhausts system resources.
