I tried to replicate your setup as closely as possible, but still couldn't reproduce this. Perhaps there is something wrong with your ObjectDock installation. Try verifying ObjectDock through Impulse. If you need to, you may download Impulse here: http://www.impulsedriven.com/impulse_setup_full.exe . Once Impulse is installed it will give you the option to create an account if you haven't already. If you already have an account, but forgot the password, Impulse also will give you the option to retrieve your account information. To verify the application through Impulse:
-Launch Impulse. Hold down shift, and right click on the entry for the application and choose "Verify Installation"
-Impulse will check the integrity of the installed application. You should be given feedback as to the state of the installed application.
-If errors are found, an update should be made available in Impulse. This is not an update to a newer version, but simply Impulse using the update mechanism to replace corrupted files.
-Once the update completes, reboot your PC.
If that doesn't do the trick, you should create a support ticket by writing in to firstname.lastname@example.org, referencing this forum thread.
