In Desktop 2.7 or Manager 2.7, create or edit an Event Log Notifications. Grab a corner of the dialog box and gradually make it smaller, watching what happens as you do so.

It's not only dialogs that can be resized like this. It's more of a estetical bug. Nothing that can mess up the functionality of the application. I think it was designed like this to allow enlargments of forms.

We will set some minimum sizes later on.
