CMutexEx Class for Safer & Cooperative Mutex Handling

[jpbro]

I run ,but I ran it at the same time and didn't see what you said about locking it in advance. Can you send a picture to take a look?

Try this in the latest version:

• Compile the demo app and run 1 instance of it.
• Run another instance of it - note that both instances are allowed to run.
• Close one of the instances
• In the remaining instance click the Extras menu, then click Block other app instances. This will acquire a perpetual mutex that will last for the rest of this app instances lifetime.
• Try to start another instance of the app - it will now show a message that another instance is running and give the option to Retry or Cancel.
• Click Retry a few times and notice that the app never starts, just keeps prompting you to Retry/Cancel.
• Close the fully running instance of the app
• Click Retry - the other instance of the app now starts.
