*user defined tactics cannot be retracted. Workaround: you may need to
retract to the beginning of the proof.
+Isabelle Proof General Bugs
+===========================
+
+* General difficulty with complex proof scripts. Since Isabelle uses
+ML as a top-level language for writing proof-scripts, Proof General
+may have difficulty understanding scripts which stray too far away
+from the standard functions, tactics, and tacticals. You will
+usually notice when a function, or whatever, doesn't get highlighted
+as you might expect. This probably has no detrimental impact on the
+interface unless you use your own "goal" or "qed" forms.
