There is a XFRX section monitored on http://www.west-wind.com/wwthreads

>Whenever we try to access the printer properties from the XFRX dialog box with Windows 7 64-bit SP1 the splwow64.exe hangs and the application does not respond again. The Windows busy mouse icon continues until we go into the processes and kill splwow64.exe.

>This problem happens on a computer at the clients site and I'm able to recreate this here.
>
>I've tried a few different printer drivers with the same results. Anyone else having this issue or found a resolve?

>Thanks,
