I have set my taskbar of windows to autohide, but suddenly it stops hiding it. even if i set the setting back to show, klik apply and close the window, go back to the settings window, set autohide again, click apply and click ok, it still wouldnt hide with whatever i'm doing.
any advice??

never mind. got it working again. the trick is to hit ctrl-alt-del(ete). kill the process explorer.exe and the go to File -> New Task and type explorer. then click OK and close the Task Manager. that's it....
