Image frames issue

Hello,

I'm having a little issue with graphic frames. When I import a graphic (either File-Import-File or Insert-Image), it is then been displayed without the standard dotted line around it. The image frame doesn't have it either. On another computer, where an identical version of FM is installed, it does have these dotted lines. I know that you can assign custom ruling to objects, but this issue looks more like some display settings. Do you know what this can be?

Thank you very much in advance for your help.

Kind regards,

Nico
