[UN-Solvable] Set the OS global cursor

[What I can do]

OS:Windows 10 @64
FPC: Lazarus 3.4
Project: set the global screen cursor for the OS

Code: Pascal  [Select][+][-]

1. uses
2.   Classes, SysUtils, Forms, Controls, Graphics, Dialogs, StdCtrls, Buttons,
3.   Grids, FileUtil,Windows;

Adding windows to users caused other problems
the CopyFile procedure from FileUtils now no longer works correct but remark the uses Windows and everything is back to normal.

Code: Pascal  [Select][+][-]

1. uses
2.   Classes, SysUtils, Forms, Controls, Graphics, Dialogs, StdCtrls, Buttons,
3.   Grids, FileUtil{,Windows};

It appears to me that some sort of conflict exist between FileUtils->CopyFile and something in the Windows->SetSystemCursor(hcur,IDC_HAND)
Anyone have a suggestion or work around?

When you add the Windows unit to the uses clause put this to the front. Because it overrides many other types and functions when it is at the end.

Code: Pascal  [Select][+][-]

1.     uses
2.       Windows,
3.       Classes, SysUtils, Forms, Controls, Graphics, Dialogs, StdCtrls, Buttons,
4.       Grids, FileUtil;

Thanks for the reply WP,
made those changes and no more errors but still no cursor change yet.
Fixed the uses clause

Code: Pascal  [Select][+][-]

1. uses
2.   Windows,Classes, SysUtils, Forms, Controls, Graphics, Dialogs, StdCtrls, Buttons,
3.   Grids, FileUtil;

Set may global variables

Code: Pascal  [Select][+][-]

1. var
2.   Form1: TForm1;
3.   aPath:rawbyteString;
4.   aCursor: TCURSOR;

did a test at TForm1.OnActivate

Code: Pascal  [Select][+][-]

1. procedure TForm1.FormActivate(Sender: TObject);
2. begin
3.   SetSystemCursor(aCursor,OCR_HAND);

but still just a normal mouse pointer
I'm doing something wrong?
