It seems to me that I used to be able to click on the WB title bar, and there would be an Amiupdate option. Maybe that is something I have lost by running DOpus5 in WB replacement mode?
I found that application with Find and clicked the icon, and was rewarded by supposedly getting an update from something like 2.24 to 2.34, but when I tried to run it, it wanted my username and password! I don't remember ever having to supply those before, and have no idea what they might be. ("New" and "old" versions are both dated 14-Feb-05.)
