My task bar icons disappear most often after running Yahoo Messenger. When I hold the mouse pointer over the lower right corner where the icons should be, it shows the name of each as if they are still there. Everything is fine after I reboot, at least for awhile. I just recently reformated my hard drive and have not downloaded anything other than messenger and aim.exe so would not expect to have any viruses or trojans. Any ideas?

this happened to me and the only thing I did was remove anything in the pc I didn't need and also delete all the temporary files. Don't know if it works for you. Also if you right click on the page where the icons should be, and in a blank space you get a downlist and you can rearrange etc your desktop icons

hello d/l spybot search and destroy,update it,run it. d/l ad-ware do the same.
