Thanks friends, and sorry for long, long silence. I wonder if screen shots cannot be taken right from the MS Windows environment without having to install a third party software? I am using MS Office 2007 over Win XP Pro.
Yes, you can do so by pressing the Prt Scr (print screen) button on your keyboard, then pasting the resultant 'grab' in your favourite photo editor for editing it, etc. Paint.Net click here is a better alternative to MS Paint for this. G
