I've recently got back from my holidays to confront a problem which started a bit before. I'm not sure if it was my influence but I don't recall any recent installations, but could it have been affected from clearing all temporary internet files including those saved by add-ons or the odd, recent dissapearance of my OnScreen volume bar.
Some of the icons on my SysTray don't seem to be there even though their processes are running. This causes problems as my anti-virus is running, but due to the issue it cannot display warnings of application connections which seem to have reset.
After browsing around I have disabled UPnP to help with this 'phenomenon' and discovered that it could be cause by systray.exe launching too late which doesn't even appear in my processes!
Thanks for any help, it is kindly appreciated!
