Click program icon twice

[Guest]

I have noticed that if I click my program icon twice quickly that two
instances of the program are started.

If I click once, normally, the program loads once. Once loaded a second
instance can not be started. How can I prevent double clicking from loading
twice?

Create a mutex on startup. When the second instance starts, the mutex will
already exist, so you can exit silently. This has been discussed a bit
already:

You can either P/Invoke, or leverage OpenNETCF to get a mutex.

I'd read about solution a while back but couldn't find info when I was trying
differing searches. Thanks for responding.
