Getting screen shots to the clipboard

Hi,

The previous version of GIMP I was using had a function to copy the
existing image to the clipboard and then I could paste it into a
document or wherever.  I have upgraded to 2.4.4 and that feature is
gone.  If I just select the normal copy from the edit menu and then
paste, nothing is pasted into my document.  Am I missing a new function
for this?

TIA,
Kim
