🚀 go-pugleaf

Are you saying when you have the pen tool selected and you hover it over an anchor point the delete anchor point tool (the pen tool with a minus sign) does not appear?

And that you have to manually select that tool in order to get the delete anchor point tool?

if so then I would say unfortunate you will have to delete the preferences. You can try to save your keyboard shortcuts and then reload them after you Trash the Adobe Illustrator Settings folder in your users preferences.

First quite Illustrator and the trash the preferences.

That should get you back to where you were. UNfortunately it will not tell you what went wrong to cause the problem.
