No, unfortunately, that is not at all what happens, Alan.

UniClip cripples the global clipboard and causes serious issues. The 
extra line feed is a just the tip of the iceberg. The linefeed problem 
could indeed be fixed easily in EasiWriter, but that would not solve 
the real problem, and since the real problem has to be solved anyway 
and that will make the linefeed problem go away, there is little point 
in changing EasiWriter.

The real problem is that UniClip prevents text with effects and styles 
to be copied and pasted within EasiWriter, and that affects not only 
EasiWriter but also copying and pasting within OvationPro (if the 
latter has been configured to use the global clipboard). With UniClip 
enabled everything is pasted as plain text.

When you copy text in EasiWriter, EasiWriter puts an EasiWriter 
document on the clipboard. UniClip asks EasiWriter to convert the 
clipboard contents to plain text and then puts that plain text on the 
clipboard itself, destroying the original rich content of the 
clipboard. The same happens with OvationPro.

So, UniClip effectively downgrades the clipboard from its original 
rich text content to plain text. That was not the idea of the 
clipboard protocol.

There are several ways of fixing UniClip. I will put them in an e-mail 
to you.
