Forum spelling checker.

Any one having a problem with the left hand of the two options - check after completing the document?.  Works ok until it has finished checking the text but when one hits the "finish checking" button it appears to go into a loop and the only way out is to hit cancel in which case it fails to make the corrections. Always was ok until a week or so ago - or is it something that I've done? The check as you type options seems to work OK.
