Question

Cursor.Current returns null in my application and HotSpot.X and HotSpot.Y returns 0 and mouse cursor disappears
Note: I am not having any customized cursor.

am having google mapwebview control in my form, am doing pinch -zoom in and zoomout through touchscreenlaptop and clicking F6 key to open another window. the cursor disappears.

I tried the following piece of code, but it's not working

if(Cursor.Current == null)
{
//Cursor.Current = Cursors.WaitCursor;

            Cursor cur = Cursors.Arrow;

            this.Cursor = cur;
        }
