The current demo of the ribbonbar in the Codejock Order Sample shows a black area in the top of the program. With a small change of oCommandBarSystem_Ribbon.pkg it works again. This code works in DF 19.0. For DataFlex 18.x a little more code is needed.

I have done some experiments with Office2016.dll and CodeJock 18.3.0. It actually works, but I wait for the first alpha or beta of DF 19.1 before using it.
