Hey Guyz i was also facing the same problm with my objectDock Plus 2. Here's a simple intruction of what i did...
1. Go to C:\Program Files\Stardock\ObjectDock Plus
Right click on the Object.exe and click on Send to----> Desktop(Create Shortcut)
2. After that rename the shortcut on desktop from "ObjectDock-shortcut" to simply "Objectdock"
3. Then Go to Start-----> All Programs-------> Startup
Right Click on Startup and click on -----> explore. Delete the shortcut "Stardock ObjectDock Plus" and it will automatically uncheck the "Load at startup" option from ObjectDock settings menu. Now cut the shortcut "ObjectDock" from desktop and paste it to Starup folder where previosly there was shortcut of "Stardock ObjectDock Plus".
4. Now restart your machine and it will work charm at every startup. Enjoy!!
and do comment...
(NOTE: Now don't check the option "Load at Starup" from ObjectDock settings ever. Otherwise the problem will still pursue.)
