I have Vista SP1 and ObjectDock Plus. For some reson, Windows notepad's icon goes invisible on the OD taskbar.
I tried giving it a different icon, I also restarted OD+ but it the icon is visible only the first time I open Notepad. If I close it and open it again, the icon is invisible (see-through) but icon is functionable, I mean, the word Notepad is displayed about the non-icon when I hover the pointer.
