Stop right there. What you're describing there is doing a remote X11 
login to the display manager [qv] running on the RPi, which starts off a 
window manager [qv]. The window manager supplied as default by Raspbian 
assumes that it's running on an RPi, and won't like being accessed over 
the LAN from XMing which is fairly old code and lacks stuff added 
comparatively recently to X11.

WITH THE IMPORTANT CAVEAT THAT I'VE NOT DONE THIS MYSELF ON WINDOWS:

What you should be doing is making sure that your SSH client (Putty or 
whatever) is set up to tunnel X11 sessions, and that the SSH server on 
the RPi is set up to make them available (it is on most distreaux).

Then SSH into the RPi to get a shell, and run your Lazarus binary. At 
that point the X11 messages originated by Lazarus are tunneled over the 
SSH session, and the Lazarus windows/forms /should/ (if Putty+XMing 
really does behave like SSH etc. does on unix) appear as separate 
windows on your client system. What's more, /if/ things are working 
properly, then cut-and-paste should work.

AGAIN, THAT'S WHAT HAPPENS ON UNIX. MY UNDERSTANDING IS THAT THE 
COMBINATION OF PUTTY AND XMING SHOULD GIVE YOU SOMETHING COMPARABLE ON 
WINDOWS, BUT I'VE NOT DONE IT MYSELF.

With apologies to the list managers if this is considered off-topic.
