Workaround to maximum size for Custom Cursors

Earlier I asked a question about having a circle tool follow the mouse around.  I was drawing the circle over the mouse and Idle_Mind gave a great suggestion (his solution is in the code snippet below) of using a Custom Cursor.  However, when I try to use a radius of say 48, it only draws part of the circle, and not the entire circle.  It seems that there is a maximum size for custom cursors and I was wondering how to get around that issue.  Additionally when I try to draw a very large circle (With a radius of say 576), I get a generic occurred in GDI+.

However, the bottom line is that I would like to have a circle tool follow the mouse and there is a possibility that this circle tool might get fairly large.

Thanks.

Public Class Form1
 
    Private radius As Integer = 20
    Private startAngle As Integer = 0
    Private sweepAngle As Integer = 360
    Private currentColor As Color = Color.Red
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        CreateCursor()
    End Sub
 
    Private Sub CreateCursor()
        Dim bmp As New Bitmap(radius * 2, radius * 2)
        Dim g As Graphics = Graphics.FromImage(bmp)
        Dim myPen As New Pen(currentColor, 1)
        g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias
        g.DrawArc(myPen, 0, 0, bmp.Width - 1, bmp.Height - 1, startAngle, sweepAngle)
        g.Dispose()
        myPen.Dispose()
 
        Dim C As New Cursor(bmp.GetHicon)
        Me.Cursor = C
    End Sub
 
End Class
