How to delete a form?

Using the latest beta version, I tried deleting a form from within the Project Window by right-clicking on a Form and selecting "Remove Form", but always got a message "The item selected in the Project Window" is not a Form." What did I miss? Thanks.

That is a bug that I introduced when I added the new capability for deleting tab pages directly on the project tree. The bug is now fixed for tomorrow's final release of OpenDCL 5.

Thanks Owen.
