this happens all the time with the 4.0 final:

************** Exception Text **************

Did it happen in the betas? I'm unable to duplicate it. Can you either send detailed instructions on how to duplicate it in our sample project or send over a project of your own that shows it?

No - just as I said it's the final. (v4.0.0232)
Project is trivial:

            private void Form1_Load(object sender, EventArgs e) {
            myEditor1.Document.LoadLanguageFromXml(@"X:\foobar\ActiproSoftware.JScript.xml", 0);
            myEditor1.Document.Outlining.Mode = ActiproSoftware.SyntaxEditor.OutliningMode.Automatic;
public partial class MyEditor : SyntaxEditor {

        public MyEditor() {
That's all. The previous beta (0231) was ok
as far as i remember.

I'm actually getting that same thing in .0231. It's like the line number is out of bounds.

Could you email over the sample project you used to duplicate the problem, any related files like the language and code that is loaded, and the steps to take to make it occur? I'd like to debug this.

phruby and I were just working wondering if it has something to do with the caret position when a language is loaded. He worked around his issue by setting the caret to offset 0 when loading a language. However I'm not sure if his and your problems are the same. I'd still like to resolve the issue by debugging your scenario and providing a fix in the next maintenance release.

Thanks for the sample. It ended up being a bug with VirtualSpaceAtDocumentEnd enabled. It's fixed for the next maintenance release. Please just turn that option off until the next maintenance release. We'll try to get it out shortly.
