When I click the spell checker icon mistakes are highlited and suggestions made. I select the correct spelling which shows in the selected box clicking replace/ replace all then exiting sp/checker and the mistake in the email body remains uncorrected. Right clicking on an error when highlited in the email body (red underlined) suggests are shown a selection made and the misyake is successfully altered. I’m using ver 9.1.2 win 10 . Not a major problem just an ongoing niggle.
