[SunHELP] CDE, .profile & aliases

I am having an issue where a user's aliases (within ~/.profile)
are appearing to not be set after logging in through CDE.  I
have verified the DTSOURCEPROFILE=true setting in ~/.dtprofile
and have tried the alias -x switch.  Any variables in the same
~/.profile are being set as expected, so for now it seems my
only issue is that when I go start an xterm this users custom
aliases are not there.  If I manually source the ~/.profile 
then the aliases are created.  The user's shell is /bin/ksh.
Any ideas?
