1) Right-click the Start icon and select Properties.
Click Taskbar tab > click 'Customize...' in Motification area' section.
Uncheck 'Always show all icons and notifications on the taskbar' (it looks like you have this on)
Click 'Restore default icon behaviors'
test to see if taht fixes the issue.
If all is OK, Re-check the 'Always show all icons and notifications on the taskbar' if you like and test again.
I hope this helps. DragonARMY http://www.facebook.com/100003250779989
