[MacTUG] Blank windows in Preview

[Dani Roloson]

> Updated to the latest 10.6.8, a Mac mini shows blank windows for jpg's
> but works fine for pdf's.
> I did a save as png and that also shows as blank.
> Quickview, Safari, and icons show both as fine.
> 
> Most web suggestions are
>  rm ~/Library/Preferences/com.apple.Preview*
> and reboot which didn't help.

Re-installing "Mac OS X 10.6.8 Update Combo v1.1" didn't help either.

> Any ideas?
