I'd boot to Safe Mode and scan for viruses.
I have 3 word processing software--OpenOffice, NeoOffice and Pages. Several days ago, I could not copy anything to either one. Almost immediately, I get the msg. that the word processing has quit unexpectedly. I thought I figured it out when I got an iCloud message asking for my password and update. I complied and the word processing worked. Doesn't make sense, but it did. But, shortly thereafter it reverted to "quit unexpectedly." At one point, I was able to copy text. But when I hit save it quit. Now, I can't open the software at all. All 3 do the same abort.
What can I do to get word processing to work?
