Whoever posted recently about a problem with Ctrl-y in surf, you might very well be experiencing a confusion about the way copy and paste works in X, rather than a genuine bug. Note that surf, by default, when you press Ctrl-y, copies into PRIMARY, and the paste command in a lot of programs pastes from CLIPBOARD.
You could change surf to use CLIPBOARD instead, as was detailed in another post. You could also try to remember to use the middle mouse button to paste after pressing Ctrl-y in surf. A lot of mouses don't have a middle button, so on a two button mouse, middle-mouse button emulation needs to be turned on. On a mouse with a scroll wheel, that scroll wheel often functions as the middle button when pressed. -- http://www.fastmail.com - Does exactly what it says on the tin
