If the drawing cursor doesn't match up with paint strokes when using a drawing tablet there as some adjustments that can fix this.
Make sure that your pointing device is set up for absolute position in your tablet driver settings. This setting is sometimes called Pen mode. Either way, you should be able to access this setting in the Windows Control Panel application that was installed with your tablet. You can also turn on Tablet Compatibility Mode in TwistedBrush. This can be found in the Preferences dialog. Access the Preferences dialog from the menu Edit > Preferences.
