'Why is the positioning of the main menu buttons related to displaying the quest log?'

The error regarding the main menu bar is triggered whenever blizzard tries to redraw the buttons which happens every time you click one of the buttons. Most of the time an error stops the rest of the process from happening, so imagine the following ...

1. Click Button
2. Frame starts being displayed
3. Update Main menu Buttons .... error ..
4. Rest of new frame display

When the error is triggered the next stage isn't executed, hence the incomplete display. This is how you sometimes see nUI not quite right, map not in the bottom, chatframes not in the right place etc. One error triggered at the wrong time can stop another process from running that is totally unrelated to the one that went wrong.
