For some reason my toolsbars suddenly changed. I was using the "classic" toolbar setup and when I consulted the manual it told me I could get that look back by clicking on view, then toolbars, then I could change my settings back to the classic configuration. According to the manual Icon I should say Edit and Icon II should say Draw. when I went to the toolbar menu it says Icon I: NOTE_WIN and Icon II: Model. I've tried turning on and off various toolbar options to no avail. Help!
On the Interface tab in Program Preferences, there is an Icon Toolbars section. You can use the drop-down selections there to define which toolbars to display.
It is possible to call another toolbar from a toolbar icon, so that might be how the active toolbar got changed.
