I am very new to coding in the Processing environment,  and I am developing an application in which I have used the controlP5 library to add some simple tabs to my main window.  Nothing really fancy....when you click on them,  they load a specific image into the main window.  My main problem is that no matter how I define the tabs,  there is always a "default" labeled tab,  which is not responsive to any mouseclicks,  like the other tabs are......and....

When my Processing program starts,  I get the main display and the "default" tab is highlighted.  When I click one of the other tabs,  it loads the image just like it's supposed to.  My problem is that I can no longer return to my initial startup display.

I know I'm doing a horrible job of trying to explain my problem,  so if anyone would like to look at my code and see what I screwed up,  please PM me.   And try not to laugh to hard when you see the code....this is the result of an old man trying to learn a new trick !!

Thanks....
Jim
