It sounds to me like what this needs is to go into XAP_App. If we ever
implemet other applications to take advantage of the app framework, at
least some of them will need spell checking, and it would be a wast to
have to implement it all again.
OTOH, our hierarchy really does look like a candiate for multiple
inheritance. (note: I am *not* proposing adding this now). It could look
like this:
XAP_App-----------
/ \ \
/ \ \
XAP_UnixApp AP_App (in wp) \- AP_App (in other apps)
\ /
\ /
Ap_UnixApp

Sometimes radical solutions are neccessary. But I don't think that this
particular case is an example of one of those times.
