Thank you for pointing to SetCapture. I didn't know it. It works
somehow, but not really good. At last it seems to complicate 
things a lot.

I did this:

  - Create a form with a some buttons having TabStop = false.
  - SetCapture(Handle); in my app's OnActivate (need to be there
    because alt-tabbing releases the capture).
  - Screen->Cursor = crArrow; in the next line, because 
    SetCapture switches the cursor to hourglass (strange 
    enough: setting the form's cursor had no effect).
  - Placing the same code in form's OnClick and OnDblClick, 
    because these events release the capture.

Here are the first problems I found:

  - Although OnDblClick gets called, SetCapture doesn't work:
    the capture remains released.
  - Alt-F4 does not work. 
  - Cannot drag the window's title bar. Neither can I use the 
    widgets for maximizing, minimizing and closing.
  - If I click the title bar without moving the mouse, the
    cature gets released.

Well, I don't know how many more problems still hide from me,
but I am not even able to solve these first ones. And I fear
that things get even more complicated when I switch from SDI to
MDI, right?. Do you know a solution? Or a better way still?

I don't want to argue, but... ;-) you call it complicated to
move and resize some images on my form? The one and only problem
is that I don't know how to make them look exactly like a button
or checkbox or another control. I guess this is what you want 
to say: "Windows is not able to render controls to another DC. 
So, although it would be the easiest way, due to the Windows 
limitations it is impossible. WM_PRINT, PaintTo and the like
don't work, the docs are all wrong." Is this your statement?
