Since a few weeks ago, and without any provocation at all, most of the icons that usually load on the taskbar with windows don't load at all. As far as I can tell the programs they belong to are still running, the icons just aren't there. I've done lots of research on this and tried a bunch of stuff to get them back, none of which seems to be working that well. I can get them back for one boot by using TuneUp's icon cache repair tool, but as soon as I shut down the computer and boot it back up, they'll be gone again. All the other tools I've tried have no effect.
Anyone have any ideas on what's going on here? Seems like the icon cache is corrupting itself every boot or something.. I don't get it.
