Why 32 by 32 4 bit BMP cursor is not displaying?

Question

Since I can't find ZoomIn and/or ZoomOut magnifying glass cursor for my program, I created my own cursor of size 32 by 32 4bit with my compiler. However, when I do assign it to my form cursor, it is not displayed at all, whereas 16 by 16 4bit BMP cursor is properly displayed as expected.

Am I missing something or is this size not allowed as of now or do I have to do something to make it work?

Here is how it is set:

Mainform.Cursor := new Cursor(baseDir+'\ZoomIn.Cur');

This is what I see after saving 32 by 32 cursor file in the windows explorer.

Normally, you should see tiny version of the cursor right next the cursor file name, but I see none.

Thanks in advance,

Windows (at least the .NET Cursor class) doesn't appear to like icons that are more than 1-bit black and white images.

32x32 bit are still supported. I tested using one of the old CodeGear Shared\Images\Cursors images, as well as a new cursor created in GreenFish Icon Editor and in the Visual Studio Image Editor (File->New File->Cursor file), using the following code:

method MainForm.MainForm_Load(sender: System.Object; e: System.EventArgs);
begin
  self.Cursor := new Cursor('E:\code\XHAIR1.CUR');
end;

So reducing the color depth to 1-bit should make it work for you.
