Noticed my spell check was not working. When I click on the underlined (misspelled) word i don't get any menu or suggestions anymore, when I move off the misspelled word an eventually do get a menu that i can chose check spelling, I press it and get Input system error. The system is being restarted.
Anyone have any ideas? Thanks in advance!

im having the same issue. how did you fix this?

Sounds like you have some sort of file corruption in the OS. I'd back up my stuff and reinstall the OS completely.
