The new tab is opened from the right most location of the tab bar by default (in the previous version, it is opened from the left most location).
If you still want to open the new tab from the left most location, you can set the NewTabAtRightMost option.
For tabs opened in the MDI window, set the NewTabAtRightMost property to False:
mditbb_1.NewTabAtRightMost=false
For painters/editors opened as tabs in the PowerBuilder IDE window, set the NewTabAtRightMost setting to 0 in the PB.INI file:
[Tabbedbar] NewTabAtRightMost=0 //0: left most location. 1: default value, right most location.
