Hi, terry, try this:

Have you solved the problem?

Thanks, I went though most of those before posting. No, that didn't solve the problem. It's intermittent and although it happens frequently it doesn't happen all of the time. One of the suggestions was to refresh, but refresh doesn't work either. In Mac I always have to force quit and start over. No malware, only 3 plugins which I disabled. No point trying safe mode since I never know when it is going to happen and the menu isn't available when this happens either.

Thanks, I appreciate the input.
