If you try and start the same programs from the Start | All Programs does these programs start properly?
Or if you double click My Computer or My Documents Icons on your Desktop do they open properly?
If yes then try deleting those other program shortcuts from your Desktop and create new ones.
The problem i have is that when i click on a certain desktop icon it flashes up the programe title.but displays a different programe name on the taskbar ? but after this the dropdown menu remains on screen cannot close the programe via the taskbar and cannot close the pc.So i have to resort to the power button on the server.why how ?
