Hi there, since a few days (I don't know exactly when it started, since I don't use Help so often) Help viewer and all other help programmes (like in Safari) keeps crashing down. OS X asks me to re-start the application, but then it crashes again. It just keeps crashing. I repaired permission in Disk Utility and cleaned all caches, but this did not improve the situation. My Mac is an iBook G4 (1.42) running Mac OS X 10.4.3 Thank you for your help!!
