Making Cursor Invisible (behind Curtain)

[moorpipe]

Thank you Gintaras. It isn't quite the same as I requested, but it gives me a starting point. In your example the cursor does not re-appear after I move the mouse within the dialog. Like I said, just like the cursor behaviour in MS Word. After I managed to do this within a dialog I have to look furher to do this generically.

Regards.
