4.2.7 RC3 Standalone True launchbar bug?

Try to delete all subkeys from the registry key:

HKEY_CURRENT_USER\Software\True Software\tlbHost\toolbars

This will reset the tlbHost. Next time you run tlbHost it request the toolbar folder. Then right-click the empty space of toolbar and select "Toolbar properties" menu item. In the properties dialog box, select the monitor you want.

Please can you backup the registry key before deleting and send it to me to diagnose the problem.
