Re: Text widget dying

[Shippy! <shippy ladron cs nmt edu>]

Ok, I've tried it on yet another machine and
I'm having the same problems. So now I have
two machines each where it does and does
not work. The only thing I can see that the
non-working machines have in common is that
they have SMP kernels. Is there anything special
you have to do for SMP kernels?
