The default unmanaged call to get the cursor position from user32.dll is as follows:

Public Module Main Public Declare Auto Function GetCursorPos Lib "User32.dll" (ByRef lpPoint as Point) As Integer

There is also a 'point' call in the SilkTest.Ntf file which causes Workbench to get confused as to which call it should be using. To prevent this, use the fully-qualified unmanaged call as shown below:

Public Module Main Public Declare Auto Function GetCursorPos Lib "User32.dll" (ByRef lpPoint as System.Drawing.Point) As Integer
