WCCOActrl.exe taking 30-40% CPU load

[Smiffy]

I have a i5 laptop with 12GB of RAM so plenty powerful to run OA.
However, my project has an issue whereby WCCOActrl Executable (WCCOActrl.exe) is premanently using 30-40% CPU time.
This is as soon as the gedi is opened and, and with no runtime panels or scripts running.
How do I go about finding and fixing the issue?

Possibly the CPU load is caused by lot of processed messages. To check ff the CTRL manager is processing messages you can use the panel System Management --> Diagnostics --> Event. man. Connections.
For details how this panel works please have a look a the WinCC OA Documentation.

Which tool have you been using to trace the CPU usage?
