Yup, you are not alone on this one. It doesn't happen very often but it happens. A error notice witll pop up and say that ObjectDock has encountered a problem and has to close. It always restarts without any problem and everything is fine. I have no idea what causes it. It happens on my XP and Vista computers. I'm running ObjectDock Plus.
It happens to me fairly often on my XP desktop (twice so far this afternoon) and I have to manually restart. I'm very disappointed in OD+ 2.0's stability. What's even more irrating is whenever I click on the button to report the problem, it spins it wheels for a minute and then fails to send the error report!
