I know its futile but...

why not make it visible only while the mouse button is held down an a particular set of keys is held down. That way they would not even be able to pick there nose while reading it. :-)

An additional step - make the text visible only on mouse enter and timer it to invisible after x seconds

Re preventing someone copying text from a confidential screen:

The best I have thought to do so far is clobber the clipboard in a timer every 1/2 second.

procedure TfrmForm1.Timer1Timer(Sender: TObject);
begin
clipboard.SetTextBuf('The clipboard is empty');
end;

Question about this - if the clipboard already had a screen image in it, does putting text in it make the previous bitmap inaccessable?

I realise that for a techo user there are always ways to capture information with special programs, I am just trying to cater for usual methods with typical users who would use the clipboard.

I guess I could require the user to close all other programs, which would eliminate other monitoring programs, but I am not sure how to check between task bar programs (which they would be happy to close) and those in the system tray (such as virus checkers which they may not want to).
