Interact with UserForm without stopping animations in slide

I'm wondering if it's possible to make a variant of the UserForm (or any other dialog box for that matter) where even if you're interacting with the dialog box, the stuff that's going on in the slide show continues.
I know how to make a non-modal UserForm (i.e., I can go to other windows while it's open), but my problem is that when I'm typing something into the UserForm or otherwise interacting with it (clicking a button, etc), the animations in the slide show stop. How can I prevent this?

For reference, my code is as follows:

Code:

---

Sub x()
    UserForm1.Show False
    DoEvents
End Sub

---

Pretty sure there's no way to do that.
