All of a sudden, for no reason that I can determine, when I try to put a new button on a card, the IDE beeps at me, and the button is returned to the Tools window. No error message. No explanation. Nothing in the Doc under "beep" or "error". Sigh. So, suddenly, I can do NOTHING at all with the IDE. Frustrating. The stack has Can't Modify unchecked. :( Jon
