MUI_HEADER_TEXT changes window title

!insertmacro MUI_HEADER_TEXT "MyTitle" "MySubTitle"

works ok for custom pages but...

Could someone explain why MUI_HEADER_TEXT also changes installer's window title to "MySubTitle" string? Is there any workaround to keep the window title unchanged ("MyApp Setup" by default)?

My bad. That window title came from the option's ini file. 🙂
