Hello
I've an application which has a Multiline text box with word wrap enabled.
I'm adding lines to the text box at run time. when ever the text goes beyond the visible capacity of the text box a scroll bar appears. the problem is that this scroll bar gets redrawn every time something is added and then the application crashes by giving the following exception.
System.NullReferenceException: Object reference not set to an instance of an object

Apart from this i periodically get the following message. i don't from where it is coming
