[Zope] anybody else see a problem with .hqx download under 2.1.1?

Hi Folks, I haven't been able to sort it out, but when I upload an .hqx (application/mac-binhex40) file and try to download it under 2.1.1 the process doesn't finish. I reverted back to 2.1.0 and it works OK. I'll snoop around and see if I can find a culprit, but I thought I'd ask here in case anyone else has figured this one out! thanks, -steve
