UniqueInstance uses the OnMessage event in combination with a timer

[han-k59]

For UniqueInstance, Is is not better to use an onMessageQueued event rather then OnMessage event. The timer is then no longer required. See attached example.

Later:
Sending parameters only worked in Windows. For Linux there is no onMessageQueued event. If have do a SimpleIPCServer1.PeekMessage(1,True) driven by timer. :(
Attached an version which works both for Linux and Windows. The Linux part is timer driven. Now I understand why there is a timer in your component.

test one instance only for windows and linux.zip
