When I use Adobe Acrobat to change PDF documents the undo button does not work, its always grey like this. How can I undo my actions???

What actions does you use?

[default50y7j2nttono]

Every, like making a comment or changing a symbol in size.

++Adding to the discussion,

If this happening with every PDF that you work with or just the current PDF that you're troubleshooting?

You can only undo commands that you executed via the menus or using the built-in tools (and even then not all of them).

You can't undo clicking a form field button, for example.

Yes i meant like clike and slide, changing a circe in size for example.

That should be possible to undo.

But it isn't, no matter what action. That's the problem. Maybe I should contact the support.

What's the exact version number of the application (You can find it out by going to Help - About Adobe Acrobat)? What's your OS version?
