Hi Yigal,
I tried the "what's this" feature on the class that you sent me.
It works fine for me, i.e., when point is in a method, it displays
[M:methodName], when point is in class, [C:className], and when it
is outside a class [???]. This feature uses an Emacs hook function.
If an error occurs in any of the hook functions, Emacs stops
invoking the hook functions. This would cause the feature to
appear to stop working.
