Imagelist bound to toolbar issues . . .binding won't stay

I'm attempting to do something that I've done many times before and it should be so simple. But, for some odd reason, it's giving me real issues this time. I have an existing VB6 form with a toolbar. The toolbar is bound to an ImageList control so that each button can be assigned it's own .ico or .bmp picture.

I've unbound the imagelist and the toolbar so that I can add the new .ico picture to the imagelist control. Now, when I try to update the toolbar, it will not let me bind the two controls together so I get no images for any of my buttons.

What am I doing wrong? I'm starting to feel really stupid about this whole thing . . .

Thanks!
