It's whatever user selected. User can change selection at runtime. But the selected cursor only show up while moving the cursor.

Here is what I want to achieve:
1. Display continuously acquired image;
2. Display user selected ROI cursor.
While try to create an example, I found the problem: Unset Busy.vi is called every times when update the image.
Problem solved. I've to move that vi to other place.
Thanks for reply.
