I see that inshaala,

did a clean install of my system recently

Hmmmm ... is that like moving to a new house? 

it seems something has happened to my button mapping on my keyboard

... and not finding everything after unpacking? 

or something weird so i couldnt put a jpg together using Print Screen

All I can say is to try ...

(1) Alt-PrintScreen followed by either

(2a) in M$ PhotoEd: Edit -> Paste as New ... or

(2b) in Photoshop: File -> New ... and then Edit -> Paste

BTW, I heard a funny story from a friend ...

It seems that someone ... ah ... 'had a bit of fun' with their supervisor ...
Since the supervisor doesn't touch-type', but always does 'hunt 'n peck',
they rearranged some of the keys on his keyboard (interchanging the
'N' and ' M' keytops was especially ... er ... cute ... [grin]).  Too bad he didn't
get the joke ... when he couldn't login, he panicked and called security.
