Is there any way to enlarge a cursor on a graph, or attach a .bmp image to it so that it shows up better?

Question

I am using an intensity graph to display position (and information) from GPS, using the graph's cursor, point only without crosshairs, to indicate the location. Sometimes it is hard to find the cursor. I would like to enlarge it, make it flash, attached an led indicator, bitmap image or something to make its location more obvious against the background data. I've thought about attaching the LED indicator, but cursor position would need to be calibrated to the screen aspect ratio. This works, but its difficult given that the graph has varying Scales. Does anyone know an easy way to make the cursor larger or more obvious using any of the methods mentioned above?

I came up with this solution but I now do not think it is what you are looking for now that I reread your posting. My example reponds to mouse clicks from the user on the intensity graph and it moves a highly customized picture control to where you mouse up. You can learn how to modify controls in the "LabVIEW� Custom Controls, Indicators,and Type Definitions" manual.
I think what you want instead is to programatically move the cursor and have an image move to the new location. I could not figure out how to do this reliably. The problem is that the cursor location is given relative to the data and there is no property that gives the postion relative to the screen. I have in the past come up with fancy algorithms for making this conversion but all my s
olutions were flaky--they did not work right when the VI as loaded from file.
Attached you will find my example. The logic for controlling the picture control movements is not finished but it gives you an idea of what you might expect with this method.
