[Xymon] Windows Client

[Neil Simmonds]

It's my experience with the BBWin client that it's the Event log part that seems to be causing the memory leak. Even when you have a decent set of ignores it still has to scan all the recent messages and on a Domain Controller or some other busy system this can be quite a large amount of messages.
