Honestly, copy and paste should not require strange flags, should it? One or the other of the Windows or the Unix method of doing copy and paste should work out-of-the-box, don't you think?
it's conterintuitive for you, but folks using mouse driven programs like ida would also find it counterintuitive if mouse would be used for copy and paste
I'm not saying this is easy to find out, but there's no other way out of it (we could however have default values in our default registry to get correct behavior for most used apps)
A+
