Summary: NullPointer on relative directory (Windows)

Initial Comment:
In Windows (at least on JDK 1.4.0), if you open one
file normally and then try to open another file by
typing in "../directory/FileName.java", the file opens
but causes a NullPointerException when setting the
current directory on the file choosers:
