Symptoms
Tabs don't respect List View header text justification when switched.
Diagnoses
The tabbed forms don't appear to initialize correctly. A bug has been logged.
Resolution
Regarding a form with tabs, add a 'When a control on the Form raises an event' event, targeting a tab's control, then add two 'Execute a View method' actions, targeting the affected view on that tab, executing the Collapse method followed by the Expand method. Do this for every tab, and it should fix the justification issues that appear when switching tabs. In a form without tabs, you could add the Collapse/Expand actions at the end of 'When the form is Initializing'.
