I have IconPacker and ObjectDock but my icons on objectdock will not stay. They keep changing. I have been on the computer all night searching and trying to fix this problem. I even loaded new icon packages to fix this. The icons on the dock keep changing back to the ugly green question mark icon. Help because it messes up my load desktop. On the change icon screen (properties) it has the icon I choose, but the icon on the dock does not change. It's just struck there.
Solve the problem: I wasn't receiving much help so got my mind to working.
1. Go to main program through menu
2. Change Icon
3. Create shortcut of new program
4. Add new shortcut on Dock
5. Drag to shortcut to new dock location
And do not delete shortcuts
This worked for me. I am posting just in case I forget. Hope this helps someone else.
