this happens if the MENUTIMEOUT makes the OSD menu disappear while a message is displayed.
Or if the driver/firmware is faulty and generates a timeout. That is how I found it, but I can also reproduce it without the driver timing out.
maybe the access to cSkinDisplay::Current is not thread safe? What happens if it is deleted while executing SetMessage?
