Comment 7 for bug 1078602

As a reply to message #6:

Thanks for your interest in Onboard and for telling us your problem.

Could you please verify whether the "Show when unlocking the screen" checkbox in the Onboard Preferences is enabled? If it is and anboard does not appear, please file a new bug (there is a link at the topright of this page to report bugs), as it is a different problem as the one from this thread.
