kklosson When a button is generated on a form (in my case it starts a process that opens an object in edit mode), it seems that regardless of the output selected, the window always displays modal in test mode. In operational mode, it displays as indicated.
aware_support All intermediate steps of a process always execute in a popup window (unless indicated otherwise in a special process property). Output selected only affects the final step and only if a process is terminated after this final step.
