David, 

I haven't seen a problem like this and find it a bit hard to imagine
how it could be occuring unless there are complicating factors
not clear from your email.  

If you can reproduce in a way I can replicate easily with 4.6,
then I would be willing to dig into it and try to fix it.  I'm not too
keen on looking into 4.4 issues though.

Best regards,
