Token Collection Error

SyntaxEditor for Windows Forms Forum

Posted 19 years ago by Ashton - Developer, Schema Solutions LLC
I am getting the following error in my app. Is there something that would cause the render of SE to try and access a token that doesn't exist in the collection? When the error occurs, the SE window is replaced with the red X, which usually indicates painting failed.

Hmm... haven't heard of that happening. Can you try and figure out steps to repro it in the sample project and send them to us?
