google003, Go to the link below and under the letter "N" scroll down to "Notification Area - Hide Icons"/"Notification Area - Hidden Chevron Missing"/"Notification Area - Icons Disappearing" where you'll find some possible solutions.
I have had this problem for about 2 days. My compuer is almost 1 year old. When I right click on my ttaskbar and select "hide inactive icons" and click apply and o-kay it doesen't hide. There is no arrow or what ever. It used to work? How can this problem be fixed? On the same day I noticed that some of my icons were missing then appeared- this is just incase but now all are there. All help is appreciated.
