Anyone know why in the last 2 days when clicking on an e-mail jpg attachment, all that happens is that I get the microsoft photo editor-jpg icon on the bottom task bar and I can not open the attahcment. Prior to the last 2 days no problem in opening a jpg attachment
Try right clicking on the photo editor icon in your taskbar and choose maximise. Sounds like you've shrunk it down at some point and it has remembered your setting.
