I just installed iWork '08 and found out that Numbers hangs whenever I want to open or create a graph. Also if I select text it hangs (spinning beach ball forever). It is completely unusable. Restarting my computer does not work. I have Numbers version 1.0.1. I am running on an intel 1.66 Ghz core duo mac mini with OS X 10.5.1. Does anyone else have that problem/Solution?
