Question: Disappearing ribbon

I know this is a "silly" question but just recently my Tool Ribbon disapears or "retracts" into thin air and I have to first click on it to get it to "deploy" downward and then when I click on it to "Insert, View, Edit..." it then retracts and is gone once I do the click.  I am forced to do 2 clicks when before I had only to do one click.  This is not efficient.  I like the Ribbon concept for Maple 2025 but this is an irritating annoyance.  If some one knowlegeable could please take a few seconds to reply to this, I would greatly appreciate it.  BTW, this just started.  In an other machine I have where Maple 2025 is located, it doesn't do this.   I am sure it is a simple setting somewhere.  I just can't find that setting.  Thank you in advance
