New VBA tools may crash PPT if no file is open

Hi all

I've coded some tools (thanks to great coding advice & corrections from here), but noticed with some, if a PPT file isn't open, it freezes / crashes PowerPoint. Is there a code I can add to my each VBA so they only work if a file is open, and don't crash PPT if no file is open?

Thank you :hi:

May we see the existing code?

I'm guessing that your tools are in an addin

Code:

---


If Application.Presentations.Count = 0 Then Exit Sub
