Yes - and you 'get away with it' in Linux - but under Windoze, it
crashes.  I'm a bit suprised at that.  If the delete operator is
the last function in the callback, the only code the compiler
will generate afterwards should be a return instruction - what
is there to crash?!?

Make a list of objects for deletion - and wipe them out at
the end of the main PUI entrypoint.

    ppeDeleteMeLater ( this ) ;

...or something.

Sure - I'm just a bit lazy about that.  I learned to program C/C++
*long* before 'const' was invented - and it's hard to shake old habits.
