While you can get this to work with the default Cygwin terminal 
(cmd.exe), you would be better off installing the mintty package and 
using that for your terminal instead.  You can configure it to behave 
like a typical xterm with respect to copying and pasting, so you may 
find that much more familiar.

To copy and paste from a regular Windows program, highlight the text and 
press CRTL-C to copy as usual.  Then go to your mintty window and paste 
using the method you configured for it in its configuration dialog.  I 
think pressing SHIFT-INS should work by default, but there are other 
options available, including middle clicking (not the default IIRC).

To copy and paste from the mintty window, highlight the text and then 
copy using the method you configured for mintty.  I have my mintty 
configured to copy automatically when text is highlighted, but that's 
not the default as I recall.  Once the text is copied, paste into a 
Windows program as usual with CRTL-V or paste back into the mintty 
window as discussed previously.

This may get corrected automatically by using mintty as your terminal, 
but it's really not a Cygwin-specific issue.  I've had similar problems 
in the past and was able to work around them by pressing either CTRL-H 
or CTRL-BACKSPACE.

My vague understanding of the problem is that the terminal sends a 
particular character in response to the backspace key, which is 
configurable in many terminals.  Mintty is one such terminal, but the 
cmd terminal is not.  Without the ability to change the character sent 
by the terminal program, you would need to be able to configure the 
remote applications to do the right thing with whatever character *is* 
sent, but that can be a tall order due to the different ways you may 
have to configure each application.

As I said, that is only my vague understanding of the problem, so it 
could be subtly or glaringly inaccurate.  In any case, however, you will 
likely avoid the problem by using mintty. :-)
