That probably means you are running bash in the standard (pre-10) Windows console. Agreed, the copy and paste in the Windows console is bizarre.
Normally bash is distributed by Cygwin and with it, the mintty terminal. In that case you just select the text with your mouse (no copy needed) and then middle click to paste. Copying off the traditional X11 approach. Works very nicely and no risk of sending a ctrl-c signal to the running program (haha!) (actually I guess that *was* the reason behind the decision for Microsofts weird "enter" to copy system of old)
