Using the latest OS X and some weird things are happening in the last\ncouple of days. One of them is that I can't add attachments to any\nemail message whereas 3 days ago it was fine. Some programs crash as\nsoon as I start them. Some install codecs seem to be missing so\nprograms I've downloaded (from the manufacturers) won't open. Its\nprobably all related. Does anyone know what to check? I've repaired\npermissions from the OS X DVD. And I just did an erase and install\nrecently.
