Sometimes, for about a week, trouble entering text in Google search (original version, not Chrome). Text is delayed a few seconds or just doesn't appear. If I refresh the screen sometimes typing is possible.

Whoops, just had a typing delay entering the above.

Have had no problem typing in Outlook Express.
