When I create a rectangular box in Autodesk Inventor 2008, shell it, and create a new sketch on any face and press E I expect to be greeted with the extrusion options. This does not happen, and a command alias input dialog appears in the status bar.
I really want to turn this off, since it has happened on other occasions as well. Since there's no other way to get to the extrusion feature, it completely halts my work.
Usually when I don't know what a feature is for and I'm not attempting to use it I expect to not see it- especially when I perform actions that don't usually bring it up. I'm not sure why the behavior has been put there. Hopefully it's not put into later versions (I've seen 2010 complaints as well) so someday an upgrade will remove the annoyance.
