I’m using the 2.8.5 client on OS X 10.4.11. After I start up the client and close the window it works normally and shows that I’m Away if I don’t use my system for while. But it doesn’t show me as Available when I return until I redisplay the client window. The client is still running but it seems it does not detect any keyboard or mouse events unless I click on the Spark icon in the dock and display the window or click on the client if it’s already open. Then it shows me as Available.
Is this normal for the Mac?
