If you have found something amiss with Drawboard PDF that you think is a bug, you can go to our Bugs Forum to post a bug that hasn't been noted previously (or vote on an existing one). Or, if you have had an 'Aha!' moment and would like to suggest a new feature, head to our Features Forum to do so.
If none of these solutions help, please contact us directly, and we will try our very best to rectify your issue!
