Ctrl+Alt+PrtScn do not appear to be working with my windows 7 Home premium. It works very well on windows XP making use of the same keyboard. I did not understood what is the cause for this. Is there a dissimilar sequence designed for screen printing the active window? How do I print the active screen? If you have any thought regarding to this issue, please let me know. Your suggestion would be appreciated. Thank you in advance.
