Incredibly useful - thanks for that.

The form now loads in workspace as it looks in UI16, but it looks like the UI16 UI policies are not fired (all the default tabs are visible) but I'm confident I know why that is, but I'm getting "this form has not been configured for workspace...."

I've tried the solution outlined here but no joy.

The form layout is there or thereabouts, but not editable and I've not found a solution for this that works for me yet.

Thanks for your help - at least I'm further along than I imagined today.
