Seems like there's never a way to force a widget such as a JComboBox to explicitly have nothing selected. The strange behaviour I'm getting is that you select a choice, and then the box collapses back down to 1 line, but it's hilighted, since that's the item you just selected. You don't get actions as the user is moving the mouse over choices in a JComboBox. So you can't, for example, update a help string as they are checking out different options. Utter inconsistency in the names of methods of Swing menus.
Runtime casting is about as evil as pointer arithmetic.
The 1.1 File docs, especially about the path seperator, are wrong. More often than not, docs fail to tell you if the index starts at 1 or 0. The behaviour of static code is evil. Often with graphics code, using either AWT or the newer 2D libraries, the first frame of animation is lost. Some flush command hasn't gone through, and yet there is no explicit graphics flush command for me to use.
