G4, 125ghz, OS10.4.6, LW 4.12.6...

I would love to open a crash log, but LW just freezes up, when I hit quit nothing happens, when I go to Force Quit, it doesn't show LW as not responding (it just doesn't do anything, can't click or move anything)

When I restart all seems fine.... but I haven't sat there & watched the freaking screen waiting for it to freeze. This has only started happening recently...
