undo() and redo() [Revisited]

I know I posted about this before, and no one had an answer.

The undo and redo functions for a richtextbox are read only, correct? So nothing you do could screw them up and make them not work, correct?

I was writting a simple text editor, everything was working great even undo() and redo(). After continually working on it, the functions mysteriously stopped working.

I have no idea why either, I wasn't even programming anything for the textbox at the time.

I've deleted and re-created the textbox as well as the Undo and Redo buttons in the menu and they STILL won't work.

Is this a known bug or something?

Alright, I figured it out.

It doesn't work when I set variables to something during the textchanged event.

So now I have to figure out a DIFFERENT way to monitor the changes in the text, ugh
