Hi all. Using the latest OS for Mac, and something keeps happening. I don't know how, but suddenly when I try to close a window, it would say "Block quote at level 1 not found" or something like that. I'd hear the ding piano sound if I try to command tab away from a window, and strangely, I'll keep getting "Ignoring next key press." I just had this happen on oribts, but there are other sites, such as audible, the ignoring next key press is said as well. Has anyone heard of behavior like this? Sometimes, if I can navigate out of the html, I can click close, and things are ok. Ohter times, I find myself having to do a hard restart which i'd rather avoid. I don't think anything else is wrong, because this isn't an every day thing. I can't submit to apple because I can't even reliably put the steps down for one of you to try and figure this out. It's just frustrating. Sometimes, turning control option lockon, then off, might key word, fix it. Thanks for any help anyone can give me.
