I don't see how this can happen if XEmacs is built --without-xim.
Suggest to the OP to try that.

IMO, this is harmless because XIM is a horrible way to do input in
XEmacs (and maybe Emacs).  The toolkit filters steal all keystrokes
and often fail to give them back.  I looked briefly at trying to fix
this, but there seems to be no demand for XIM and any fix would be
pretty fiddly, demanding unending maintenance on average ;).

If people really want to use uim as an input method in XEmacs, I can
revisit the issue, but they'll need to post a RFE to the tracker
and/or xemacs-beta.
