Enviroments: jdk6u18 b03 (not reproducible on earlier builds), Windows Vista
1. Run JTable demo (for example, http://java.sun.com/docs/books/tutorial/uiswing/examples/components/SimpleTableDemoProject/src/components/SimpleTableDemo.java)
2. Move the cursor over JTable, try to resize the columns
3. Note the cursor type is still "default" (but not "resize" which is expected).
This is an unfortunate regression of the fix for #6884066
SwingUtilities2.shouldIgnore() skips all mouseEvents with no pressed mouse buttons
