ok, i downloaded appdelete and the little white rectangle thing for it is on my desktop, but whenever i click on it all of the icons on my desktop disappear for a few seconds, as does the bar at the top with the time and stuff on. then the icons and the bar come back, but it won't let me open appdelete. the same is now happening if i click to try and open another program on my desktop, no apps will open. pictures and folders are fine. it's really beginning to bug me, and i have no idea what to do.
