I have 4.03 and no problems with rebooting or freezing or screaming.
However, a week ago my Silver Maple finally finished dumping little helicopter seeds into my gutter and the leaves came in. There was new growth that was blocking my LOS to 119 partially. I have timers set for channels on 119 and the box was rebooting regularly trying to pull in that bird. I got out and trimmed up my LOS and my 622 is back to humming along without trouble.
