While flying this weekend, I got lots of alerts for airspace and traffic. Normally, I don't use the "more" button, and the alert bar hugs the bottom of the screen (and I use portrait mode, if that makes a difference).
On my outbound leg, I did play with the "More" button to get add'l traffic details. Unfortunately, after the first time I used the "More" button, which increased the size of the alert window, all subsequent alerts appeared on the screen as if at the top of the expanded window.
In other words, it was as if my normal ~2 line alert that normally hugs the bottom of the screen moved up about 2 inches on the screen (I could see my moving map both above and below it).
This behavior persisted for the remainder of the flight, and even persisted after a poweroff / back on cycle.
Is this a bug? Is there a way to force the alert bar back to the bottom of the screen after choosing "More"?
