How can I Enable ghost pointer?

How can I Enable ghost pointer?

[Joel Moots]

I use XWin and XDM to connect to an HP-UX box for work, after connecting
remotely to a Windows Terminal Server. The mouse cursor over an X window
has always moved rather slowly/jerkily, which is expected. However, the
other day, due to some fluke interaction between Windows and X, the
Windows mouse pointer was also appearing while I was in an X window. I
*loved* this, as I knew exactly where my X pointer would wind up without
having to wait for it.

Anyway, I cannot repeat this behavior at will, even if I do not use the
-lesspointer option to XWin. Is there an easy way to always enable the
Windows pointer (or rather not to disable it) without having to
modify/compile XWin myself? I searched the mailing lists but the threads
generally seem to be about the subject of how to disable this behavior..

TIA,
