It looks like this is caused by the 'document.getElementById("categories");' at the bottom of change_default_view.xul. With that line, Greasemonkey decides not to add itself to the list. Without that line, if you close the AM with the search tab selected, it loads addons://updates/available rather than the default tab. Bizarre. (That line isn't even supposed to do anything!)

I will try and fix this properly, but for now the workarounds are either to pick "Manage User Scripts" from the GM menu/toolbar icon, or to use Scriptish instead.
