LR 4 - upgrading previews

[tech4all]

Went from LR 2 to LR 4. How long does LR 4 take to upgrade previews? I have about 4,000 RAW files from a Canon 40D. The status windows been stuck on upgrading previews for about ten hours. Is this normal or is it stuck?

Specs:

Mac Pro Dual 2.8GHz (quad core)
4GB RAM
ATI 5770 GFX card

Thanks!

Nevermind I resolved the issue. Guess it was stuck.

But I did encounter some odd issues regarding Time Machine. See this thread please.
