Refreshing System Tray

Hi guys!



I'm trying to refresh the Taskbar Notification Area (region near the clock) in order to get rid of icons that belong to processes that have been killed.



The approach I was using was to hover over the system tray using the mouse but this approach has been proven to be unsuccessful because I sometimes get an "Overlapping Window" error from the system tray and it fails to hover over the icons in order for them to disappear.



I'm currently writing code using JScript but a CMD command would be great too.



Do you have any ideas on how I could do this?



Thanks,

Sergiu
