Backup reminder - cancel option?

[loweskid]

I sometimes have IMatch running on a second monitor which has a lower resolution than my main monitor.  If I then move it to the main screen it's in a window smaller than full screen.  Occasionally, when I attempt to hit the expand icon I've accidentally hit the close icon instead, which brings up the Backup Reminder dialogue.  There doesn't seem to be a way of closing this dialogue without closing Imatch.  For the sake of idiots like me, could you please add a 'Cancel' option to the Backup Reminder dialogue.

This dialog is called from the shut-down routines in IMatch. IMatch is almost closed at the time you see this dialog, no way to restart it from there.
