When I am in a Java file and press CTRL-O to open the members overview the cursor should be in the Filter Dialoge box.
The first thing i usually do when pressing CTRL-O is to type in a method name, but since the cursor is still in the java editor, i acutally change the source code, which is confusiong.
Interestingly, in some circumstances the cursor IS in the Filter box, but mostly not.
