Anyone had problems in XE6 with changing the base form that lots of other forms inherit from? I made one change and some but not all of the child forms have now had one of their components removed from the form. It is very annoying as it is the back button. Plus the align in my bottom toolbar is not working correctly. I have two buttons one aligned left the other aligned right. Now the back button is attempting to disappear the button I have aligned right is now on the left and it is set align right. What the hell is going on?
