This has cropped up many times over the years and has probably been answered but I have not been able to find a suitable solution or have forgotten .
So, imagine you have a BO Form with a Reference Query on the form in with you can Add, Edit or Delete child records.
If you EDIT that BO Form directly from a screen button then no problem. The form can be in a PopUp and still functions correctly.
But if you execute and EDIT BO Using... from a Process and it displays a Popup... then the behaviour is different.... If you try and Add a new record to the Reference Query, then Aware asks if you want to cancel the current operation....

To avoid this, I generally always display the Form in a New Tab which generally is fine.
But this looks stupid when it is only a small form with a small amount data or in my current issue where I cannot force the Form to open in a New Tab.
I am calling a Process from the Context Menu of a Schedule Timeline Control and I can indeed select the Output there as New Tab....
It passes a BO Instance to the called Process... then finds the required record of a related BO and then I execute an EDIT of that found record....
No matter what I do I cannot get it to open in a New Tab. Always displays as a Popup and then of course the Cancel dialog kicks in when I try and add a child record to the reference Query.
Can anyone advise a way around this or refresh my memory of a previous solution please?
