Preview and command-G search next

[pedz]

Using Leopard:

I'm wondering if it is just me. Command-F does a search. Command-G is suppose to search next. It just kinda makes Preview quiver and shake. Sometimes is searches forward one or two and then loops around. Other times, Cap-Command-G works fine (backward search) while forward is broken. Other times they are both broken.

I searched and did not find others talking about it. Its just totally broken... doesn't anyone else but me care? Or, do I have something set up funny?

Thanks,
