Removing/changing components using HFSLIP source causes freeze

[heffalump]

I'm wondering if anyone else has done this? Use HFSLIP to slipstream a clean source + servicepack + hotfixes and then run nLite over the SOURCESS result?

I did just that with Windows 2000 and the resulting install freezes at "Saving Settings" with the progress bar right near the start. Then I tried it again but this time UNticking Components i.e. only adding tweaks and enabling/disabling things. I used a copy of the SOURCESS each time so was not running repeatedly over an nlite'd source. This time the freeze didn't happen.

Question is why does this happen? Any way to overcome it? I'd like to remove a few components such as Tour from a HFSLIPed source.
