I don´t want the my app. to process any keyboard or mouseevents while the cursor state is crHourGlass.
What is the best way to do this ? (Considering overhead and ease of implementation)

Make your form disabled - Form1.Disabled := True;

I tested it with all forms: Normal, MDI, everything! I set the ENABLED property of the FORM to FALSE and it can't receve any clicks, key strokes, menu selects, move_window message - nothing! You can't even close it with Alt+F4!

What's wrong here?

(PS sorry, there is no such property as Disabled like i posted in the first comment, it's "Enabled" instead...)

The non-modal forms created by the form, can still recieve input, but you´re right, it works for the form where I set enabled:=false, sorry.
Is there any easy and fast way to disable all "child" windows.
I could traverse TForm.Controls and do it that way, but that seems to be slow ?

ps. Just answer the Q again, I will award you the points.

You can disble all child windows like this:

  with Form1 do for I := MDIChildCount-1 downto 0 do
     MDIChildren[I].Enabled := False

-I don't think it's slow...

Sorry for the misunderstaning and good luck,
