Mouse Global verstecken?

[schwa226]

Mein Programm macht Autostart und da möchte ich die Mouse verstecken.
Wird die Mouse bewegt wird sie wieder angezeigt. Nach einem Timeout wieder ausgeblendet.

Nun habe ich aber eh Probleme:

Delphi-Quellcode:

var
OldCursor : TCursor;
NewCursor : HCursor;

const
  // Yin cursor AND bitmask
  ANDmaskCursor: array[0..127] of byte = (
    $FF, $FF, $FF, $FF, $FF, $FF, $FF, $FF,
    $FF, $FF, $FF, $FF, $FF, $FF, $FF, $FF,
    $FF, $FF, $FF, $FF, $FF, $FF, $FF, $FF,
    $FF, $FF, $FF, $FF, $FF, $FF, $FF, $FF,
    $FF, $FF, $FF, $FF, $FF, $FF, $FF, $FF,
    $FF, $FF, $FF, $FF, $FF, $FF, $FF, $FF,
    $FF, $FF, $FF, $FF, $FF, $FF, $FF, $FF,
    $FF, $FF, $FF, $FF, $FF, $FF, $FF, $FF,
    $FF, $FF, $FF, $FF, $FF, $FF, $FF, $FF,
    $FF, $FF, $FF, $FF, $FF, $FF, $FF, $FF,
    $FF, $FF, $FF, $FF, $FF, $FF, $FF, $FF,
    $FF, $FF, $FF, $FF, $FF, $FF, $FF, $FF,
    $FF, $FF, $FF, $FF, $FF, $FF, $FF, $FF,
    $FF, $FF, $FF, $FF, $FF, $FF, $FF, $FF,
    $FF, $FF, $FF, $FF, $FF, $FF, $FF, $FF,
    $FF, $FF, $FF, $FF, $FF, $FF, $FF, $FF
    );

  // Yin cursor XOR bitmask
  XORmaskCursor: array[0..127] of byte = (
    $00, $00, $00, $00, $00, $00, $00, $00,
    $00, $00, $00, $00, $00, $00, $00, $00,
    $00, $00, $00, $00, $00, $00, $00, $00,
    $00, $00, $00, $00, $00, $00, $00, $00,
    $00, $00, $00, $00, $00, $00, $00, $00,
    $00, $00, $00, $00, $00, $00, $00, $00,
    $00, $00, $00, $00, $00, $00, $00, $00,
    $00, $00, $00, $00, $00, $00, $00, $00,
    $00, $00, $00, $00, $00, $00, $00, $00,
    $00, $00, $00, $00, $00, $00, $00, $00,
    $00, $00, $00, $00, $00, $00, $00, $00,
    $00, $00, $00, $00, $00, $00, $00, $00,
    $00, $00, $00, $00, $00, $00, $00, $00,
    $00, $00, $00, $00, $00, $00, $00, $00,
    $00, $00, $00, $00, $00, $00, $00, $00,
    $00, $00, $00, $00, $00, $00, $00, $00
    );


OldCursor := Screen.Cursor;

  // Create a custom cursor at run time.
  NewCursor := CreateCursor(HInstance, 19, 2, 32, 32, @ANDmaskCursor, @XORmaskCursor);

SetSystemCursor(NewCursor, OCR_NORMAL);

Nun ist die Mouse versteckt.

Aber wenn ich nun per
SetSystemCursor(OldCursor, OCR_NORMAL); versuche ihn wieder zu restoren, bleibt er versteckt?
