Single Instance of Application problem

I have the following code to allow a single instance of my application.

VB Code:

Dim process() As process
 
        process = System.Diagnostics.Process.GetProcessesByName("AppNameHere") 'System.Diagnostics.Process.GetCurrentProcess.ProcessName)
        If process.Length = 1 Then 'Not already running
            Return False
        Else 'Already running
            Return True
        End If

My problem is that when the icon for the application is double clicked to launch, and then double clicked again to launch before anything has loaded - both attempts are caught as a multiple instance and nothing loads.

Is there a way to make this load the first instance and not allow any others even during the loading process?

I have also tried using a mutex to the same results.

Using Mutex is much faster here is an example:

Thanks! That was exactly what I was looking for! Works great!
