I've been developing an Excel App with about 4 User Forms. Recently, all the
controls in my Toolbox, except for "Select Objects", have dissappeared. When
I right-click and select "Additional Controls...", sure enough everything is
unchecked. So, I go ahead and re-add the "Microsoft Forms 2.0..." controls
and they show up again in my toolbox. However, if I exit the VBE and Excel
and go back in, once again my Toolbox is empty. What's going on??
