Cursor is jumping in graphics screen and will not snap to points on curve.
Solution
If the user is using a Logitech device, there is a setting called Smart Move which can cause this behavior if it's enabled. For example, the user was creating a Studio Spline and the cursor was jumping to the G1 G2 G3 constraint tab which appears when selecting a point for the spline. This setting was also causing the cursor to jump to the lower right area of the graphics window when an alert message appeared. Disabling this setting resolved the issue.
