Just wanted to add my solution related to above in case it helps someone else. As my machine had loads of memory (4GB) some time in past I had disabled the paging executive to speed it up even more. Turning it back on let me be able to paste full high resolution screens. (HKLM\System\CurrentControlSet\Control\Session Manager\Memory Management value:DisablePagingExecutive set to '1') Regards, Bryce.
