I'm having a problem with listBox stealing mouse clicks from my program.   I made a simple example to show this.  I didn't have this problem when I was using the older scrollList, but it seems to exist in listBox...

I am attaching the controlP5 website example for using ListBox.   I added a few lines to controlEvent() to set the label of the listbox after it is selected, and then automatically close it up.    This part works fine, but then the next mouse click is always stolen, it doesn't re-open the listBox, or if you had any other controllers on the screen, it doesn't activate them.  Wondering if this is a bug or there is something I'm doing wrong?

thanks!
