Thanks.

Unfortunately that type of Panel does not seem to have consistent tab properties. In order to get tabbing you have to explicitly add Panel from Display controls. This adds a dPanel which does allow tabbing. I figured this out by running your bizobj tutorial. That app allowed tabbing between text boxes. The confusing part was that in the 'empty' ClassDesigner form tabbing worked and in the 'live' form it did not. Also tabbing worked in the 'live' grid control even though it was not on a dPanel. > > In the case that the panel does exist please save the form as a "Runable > App" and run it from a command line shell.
