I have Vista Home Premium and after using my pc for a while none of the icons on my taskbar at the bottom will work including the windows one. I am still able to browse but the only way to fix the problem is to log off and then logon again. Also when they are working and I click on Windows icon bottom left it does not have any quick launch icons and I have to click on Programs to load anything. Has anybody got any ideas what is going on as its really annoying me.
