Diff File v1.1

Version 1.1 is available on the twiki at:

- The DiffPanel.goToFirstDiff() method is
called to prevent the scrolling problem in v1.0.
- There was a suspected conflict with the
menu accelerator used. (The JAD plugin used the same
accelerator, and this caused the IDE to hang.)
- The Diff view is now a JFrame instead of a JDialog.
- The class has been reorganized (not for the last time).
- The files are now both loaded as VirtualFile instances.
- The DiffPanel now uses the file type to allow syntax
- Several other enhancements to the code that do not
have any effect on functionality.
