I really need to use an active X textbox to have a scrollable text field, but when I try to edit the properties I get the following error (attached in image as well).

System error: &H80004005 (-214746759) Unspecified error.

Completely unhelpful.

I searched around online and have not been able to find any useful help.

Could somebody please either:

A) Tell me how to fix this. or

B) Give me another scrolling text field alternative.

I have a significant amount of text I need to talk students through on a page, and putting each bit on a news slide as I move around isn't practical.
