If the cursor is positioned at the very beginning of a document and InsertText() is called, line modifications markers do not appear for the inserted text.

Hi Marianne,

I'm not seeing that behavior. Could you provide repro steps? Thanks!

I can repro it reliably in the sample app by taking the following steps (if I understood why it was happening I could repro it with fewer steps ;))

-Launch SDI Sample App
-Select and copy the TestClass summary comments
-Move the cursor to Line 0, column 0 (very top of document)
-Hit spacebar twice
-Move the cursor back to the start position by using the left arrow key (hit it twice)
-Paste copied data (this should work)
-Undo via CTRL-Z
-Hit the Delete key once (so the first line text is now one space closer to the cursor which is still at the top of the document
-Paste again (you will now see the problem)

This is not a big problem in itself but I have users that frequently copy and paste into the top of documents and when this bug hits it is often followed by the following exception. Hopefully this will allow to fix the first issue so that the exception will be taken care of as well: 
System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

Hi Marianne,

This should be fixed for the next maintenance release. I haven't seen the exception occur but if you see it happen after the update, please see if you can make a sample project that repros it and send it over. Thanks!
