Yes, it should be done at the icon level because most of times, when developers are putting the code to detect inside the setup program, the second instance will not even be able to load because of a low memory.

Having it at the icon level will also give you instance switch to your application or load it.

We normally use a small C program for that. If you want I can put you in contact with my C resource and he'll talk you more about his C detect program. A few of us, here in the Universal Thread, are already using his routine.
